Abstract

Neurodegeneration with brain iron accumulation (NBIA) is a collective term to indicate a group of neurodegenerative diseases presenting accumulation of iron in the basal ganglia. These disorders can result in progressive dystonia, spasticity, parkinsonism, neuropsychiatric abnormalities, and optic atrophy or retinal degeneration. Onset age ranges from infancy to late adulthood and the rate of progression is very variable. So far, the genetic bases of nine types of NBIA have been identified, pantothenate-kinase-associated neurodegeneration (PKAN) being the most frequent type. The brain MRI “eye-of-the-tiger” sign, T2-weighted hypointense signal in the globus pallidus with a central region of hyperintensity, has been considered virtually pathognomonic for PKAN but recently several reports have denied this. A significant percentage of individuals with clinical and radiographic evidence of NBIA do not have an alternate diagnosis or mutation of one of the nine known NBIA-associated genes (idiopathic NBIA). Here we present an adult-onset case of “undiagnosed” NBIA with the brain MRI “eye-of-the-tiger” sign, and with psychotic symptoms which were successfully treated with antipsychotic and mood stabilizer medications. Here, the term “undiagnosed” is used because the patient has not been screened for all known NBIA genes, but only for two of them.

Hemochromatosis-induced bipolar disorder: a case report.

Gen Hosp Psychiatry. 2012 Jan-Feb;34(1):101.e1-3. doi: 10.1016/j.genhosppsych.2011.04.013. Epub 2011 May 31.

Abstract

OBJECTIVE:

A patient presenting with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, bipolar disorder was found to be affected by high iron hemochromatosis. This prompted us to explore the relation between bipolar disorder and iron overload.

METHOD:

We report the case and review the peer-reviewed literature focusing on mood symptoms in patients with hemochromatosis or iron overload. Animal studies of brain effects of iron overload are summarized. High iron hemochromatosis was confirmed by genetic testing, and treatment was instituted to address iron overload.

RESULTS:

Patient’s bipolar symptoms completely subsided after phlebotomic reduction of iron overload.

CONCLUSION:

Clinicians should explore the possibility of iron overload and seek genetic confirmation of hemochromatosis in resistant bipolar disorder to avoid unnecessary medication.

Schizophrenia-like psychosis and aceruloplasminemia

Schizophrenia-like psychosis and aceruloplasminemia

Abstract

Schizophrenia-like illnesses occur in a variety of medical and neurological conditions but to date have not been described in association with aceruloplasminemia. Aceruloplasminemia is an autosomal recessive disorder of iron metabolism which leads to iron deposition in the basal ganglia, thalamus, cerebellum and hippocampus and which usually presents in middle age with extrapyramidal symptoms and dementia. We describe a 21-year-old woman on treatment for aceruloplasminemia who presented with schizophrenia-like psychosis and declining function in the absence of neurological signs. Neuropsychological testing showed significant dominant hemisphere deficits. Magnetic resonance imaging showed bilateral iron deposition in the cerebellar dentate nuclei and thalami, frontal atrophy, and periventricular white matter hyperintensities. Functional imaging suggested global hypoperfusion. The clinical, cognitive and imaging findings were not typical for either aceruloplasminemia or schizophrenia alone and the possible relationship between the two disorders is discussed with particular reference to implications for our understanding of schizophrenia.

Keywords: aceruloplasminemia, schizophrenia, psychosis

Introduction

Numerous medical conditions are known to produce psychotic symptoms that resemble schizophrenia, including metabolic and neurological disorders (Cummings 1996). We describe a young woman with schizophrenia-like psychotic symptoms and functional decline in the context of diagnosed aceruloplasminemia, a disorder which has not been previously associated with psychosis.

Case history

BB was a 21-year-old woman referred for neuropsychiatric assessment on the background of a psychotic illness and a confirmed diagnosis of aceruloplasminemia. BB’s family had noticed an initial 18-month period of functional and social deterioration, poor school performance, social withdrawal, and periods of verbal aggression. She was initially treated by her general practitioner with fluvoxamine, but later deteriorated with frank persecutory delusions, auditory hallucinations, aggression and poor self-care over the subsequent 6 months. The local mental health team began risperidone 3 mg/day, which treated the positive symptoms but did not arrest her functional decline. BB completely avoided all social contact, only watched television and was unable to manage her activities of daily living. She was referred for neuropsychiatric assessment to further elucidate the contribution of the aceruloplasminemia to her cognitive and functional abilities.

 

BB had no formal psychiatric history. She had mild learning difficulties as a child, but attended mainstream schooling. At age 15 she had seen a school psychologist after telling other students she was going to be reborn as a prince. BB had been diagnosed with aceruloplasminemia at age 20, after detection of abnormal liver function and hyperferritinemia of 1700 μg/L (15–200). Liver biopsy confirmed significant iron overload without fibrosis, and desferrioxamine 20 g thrice weekly was initiated. The diagnosis of aceruloplasminemia was highly suspected because a paternal uncle had been diagnosed with the disorder. The patient and her maternal uncle share a common, unique mutation for this disorder. BB’s uncle had been described by the family as suffering long-standing behavioral problems but had never been given a psychiatric diagnosis. There was a history of consanguinity, with her parents’ grandparents being first cousins.

BB’s delivery was normal but for a prolonged rupture of membranes. She walked at 12 and talked at 15 months. She was a shy and clingy child at school who had verbal and social difficulties. She left school in Year 11 and attended a technical college where she also struggled. She had not worked or attended school since the age of 18. There was no history of substance abuse.

On mental state examination, she was cooperative but only established superficial rapport. Speech was of normal rate and volume with limited spontaneity. Mood was euthymic and affect reactive, although blunted. At the time of assessment there were no psychotic or depressive symptoms and no insight into her previous symptoms or functional impairment.

On bedside cognitive testing, she scored 25/30 on the Mini-Mental State Examination (Folstein et al 1975), and 75/100 on the Neuropsychiatry Unit Cognitive screening tool (NUCOG) (Walterfang et al 2006), each significantly below expected age norms. Hence, the patient was referred for a neuropsychological review, and information from an earlier assessment was obtained as a baseline. Physical examination was unremarkable. She had some mild conjunctival pallor but no Kaiser-Fleischer rings. She had no abdominal organomegaly. There were no abnormal movements, primitive reflexes or other neurological signs.

BB had normal electrolytes, hepatic, renal and thyroid function. Hemoglobin was low at 101 g/L” (115–150) with normal platelet and white cell counts and B12 and folate levels. Serum ferritin was still elevated at 688 μg/L (15–200).

Magnetic resonance imaging (MRI) showed global atrophy, most marked over the frontal lobes. She had a greater-than-expected load of periventricular white matter hyperintensities, and a thin anterior callosum. Iron deposition was evident in the dentate nucleus of the cerebellum and the thalamus, and to a lesser degree throughout the whole cerebral cortex, but not in the basal ganglia (Figure 1). Single-photon emission computed tomography (SPECT) showed global hypoperfusion. MRI of the abdomen showed no evidence of ovarian iron deposition. EEG was normal. A screen for lysosomal and other storage disorders on peripheral blood lymphocytes and cultured fibroblasts was normal.

Case Report: Psychosis in an adolescent with sickle cell disease

Abstract

Anxiety and depression are well documented complications of adjustment in sickle cell disease (SCD), but psychosis as a direct complication of or adjustment in SCD is uncommon. This article reports a case of psychosis in an adolescent with SCD. It advocates for further study on the relationship between psychosis and brain tissue silent-infarcts in these patients and the urge for alertness on the part of health care professionals regarding a holistic approach to the management of these children and adolescents with SCD.

Case presentation

Reasons for evaluation

O.J, a seventeen year old male adolescent presented at the psychiatric outpatient facility of Federal Psychiatric Hospital, Calabar, Nigeria with a second episode of mental illness. He is a known sickle cell disease (SCD) patient with Hemoglobin genotype Hb.SS from South-south region of Nigeria. He was single and of Christian faith. He had just completed his high school education. He was brought by the father and an elder sister to the psychiatric out-patient facility on account of being talkative, verbal and physical aggression, poor sleep, accusing house help of witchcraft and refusal to eat his meals, believing they had been poisoned.

History of psychiatric and general medical illness

He was apparently well until 4 weeks prior to presentation when he was noticed to be talkative and often talked out of the theme of discussion. He was easily provoked and agitated. He had physically fought the house-help on account of “discovering” her to be a witch and shouting “blood of Jesus”. He had seen so many small children who were alien to the family members in their apartment, this O.J attributed to mean other members of the witchcraft society. He also saw other members of the family as being small in size in his perception while he was growing taller in size in comparison to them. He had not been sleeping adequately most part of the night. When not asleep he would be found talking to himself, praying excessively and reading the Bible. He complained that people around him knew what he was thinking without telling them. He admitted to hearing his thoughts being spoken aloud. He refused to eat the meals prepared at home, believing that the meals were poisoned and that he might be inflicted with witchcraft on eating. There were no associated depressive symptoms but he had expressed suicidal ideation in the past usually during periods of bone pain crises, however there was no definitive suicidal plan. The first episode of mental illness occurred at age fifteen and was characterized by poor sleep, visual hallucination, persecutory belief and easy irritability. It lasted only three weeks following treatment in a private hospital of which details could not be ascertained because of poor record keeping.

He was diagnosed with SCD for the first time at the age of two during a bone pain crisis. He had had blood transfusion thrice at ages four, nine and twelve years following hemolytic crises with packed cell volume (PCV) lower than eighteen percent on each occasion. He had been stable after the last blood transfusion except for intermittent episodes of bone pain crises occurring about four times a year.

Family, development and social history

He was born to a monogamous family, third of three children of the parents. The mother died from complications of breast cancer when O.J was twelve years old. He said he missed the mother because she was most time his source of comfort during episodes of SCD crises. O.J and his two elder siblings lived with their father, a female house-help and their step-mother, whom the father married a year after O.J mother’s death. O.J’s siblings were well adjusted. Cordial relationships existed among the family members except for frequent frictions between O.J and the step-mother which revolved around O.J’s refusals to join siblings and house-help in various house-hold chores. The father was a middle class income earner and rarely stayed around with the children because his insurance work required frequent traveling. O.J and his siblings spent most part of their time with the house-help and their step-mother. None of the patient’s siblings suffered from SCD, but the father had sickle cell trait with Hemoglobin genotype (Hb.AS). There was no positive history of mental illness in the family.

Pregnancy, birth, neonatal and childhood history were uneventful except for periods of SCD crises. Developmental mile stones were within normal. He completed high school education a year prior to this episode of mental illness, made good grades and was planning further studies.

O.J was described as reserved with few friends, often kept to himself, did not like group activities and occupied his time with reading.

Mental state evaluation

O.J was found to be frightened and agitated but well dressed and groomed. There was loosening of association in his speech and he had abnormality of thought possession. He had paranoid beliefs directed at the house-help and step-mother and experienced visual hallucinations. Orientation in place, person and time was good. Immediate and long term memory were good but short term memory was impaired and he could not concentrate. O.J had a fair judgment and insight into his clinical problem as he thought he needed some help and medications to calm his “nerves”.

Physical examination and laboratory investigations

Physical examination revealed a pale young man with a tinge of jaundice and slight dehydration. He had about four centimeter below the right costal margin hepatomegaly. Neurological Examination revealed no gross abnormality. Examinations of other systems were essentially normal. Magnetic Resonance Imaging (MRI), though recommended, could not be done on this patient because of non-availability of facility for this procedure in the geographical region where the patient was managed. Packed Cell Volume (PCV) was twenty two percent. Blood film showed reticulocytosis and one plus of malaria parasite (Plasmodium Falciparum). Total and differential white blood cell (WBC) counts were within normal range. Electrolytes and urea were essentially normal. Liver Function Test (LFT) did not reveal any abnormality.

Diagnosis and treatment

The working diagnosis made on initial assessment was that of paranoid schizophrenia (F-20) and co-morbid sickle cell disease (SCD) (D-57) and malaria (B-50) based on World Health Organization (W.H.O) International Classification of Diseases, 10th edition (ICD-10). Narrowing down on the diagnosis of paranoid schizophrenia without considering organic delusional (Schizophrenia-like) disorder (F 06.2) secondary to brain tissue silent-infarcts was not possible because of the limitation of in-exhaustive neurological investigation of the patient through MRI. Psychotic symptoms were treated with Risperidone 2 mg daily and he had family therapy sessions. Psychotic symptoms resolved completely after four weeks of in-patient treatment. He was encouraged to join the sickle cell club in his environment to improve his social activities and to share his experience and “pains” with other SCD patients and their parents. He was referred to a Hematologist and advised on regular hematinics and prophylactic anti-malaria intake. He was maintained on Riperidone 2 mg daily which he took for another four weeks before it was tailed off following his discharge to the psychiatric outpatient facility. Liaison service had been developed with the Hematologist in form of periodic feed back report on O.J and he had been completely stable and without psychotic symptoms in four months of follow-up.

Discussion

Factors associated with the second episode of mental illness in O.J were identified as adjustment to coping with SCD crises, pre-morbid schizoid trait, and loss of mother through death to complications of breast cancer at the age of twelve.

Sickle cell disease (SCD) is found prevalent in black race, Arabians and the Caribbean [1]. It is a hereditary and chronic medical condition that encompasses sickle cell anemia (SCA) (Hb. SS), sickle cell hemoglobin C disease (Hb. SC) and sickle cell B thalassaemia (SB. Thal.) and the condition is characterized by red blood cell sickling patho-physiology that results in anemia, chronic organ damage, acute episodes of pain crises, infection, splenic sequestration, acute chest syndrome, stroke among others [1]. SCA (Hb. SS) is the most common of SCD and carries the most debilitating prognosis [1]. SCD occurs in about two percent of Nigerian population [2].

Adjustment difficulties have been documented among children and adolescents with chronic medical conditions like SCD [35]. Anxiety and depression are well documented complications of adjustment in SCD [69]. However, psychosis as a direct complication of SCD or of adjustment in SCD among children and adolescents is infrequently reported. Health care professionals need to be alerted on the possibility of psychosis complicating SCD among affected children and adolescents.

Considering the diagnostic limitation imposed by the in-exhaustive neurological investigation of this adolescent through MRI, the co-morbidity of psychosis and SCD in this adolescent would be discussed in light of the three possible dimensions:

Two completely independent disease conditions co-existing

It is possible that the psychotic symptoms and SCD in this patient co-existed completely independent of each other.

Organic psychosis complicating brain tissue silent-infarcts

Brain tissue silent infarcts are not uncommon among SCD patients [10]. Statius van Eps et al [11] reported transient psychosis in association with cerebral infarction in a thirty five year old patient with Sickle cell Hemoglobin C disease (Hb. SC). That psychosis in this patient was complicating brain tissue silent infarcts cannot be ruled out in view of the acute and transient nature of the two psychotic episodes experienced by this adolescent. Future investigation of brain tissue silent infarcts and psychosis among SCD patients is desirable because of the red blood cell sickling patho-physiologic process of the condition. Isolating brain tissue silent-infarcts as etiological factor of psychosis in SCD patients would obviously pose further treatment challenge in tackling the co-morbidity.

Psychosocial adjustment to SCD and other life events precipitating psychosis in an adolescent with ongoing schizophrenia

Stressful life events had been associated with the onset of schizophrenia in individuals predisposed [12]. This adolescent, aside facing the psychosocial problem of adjusting to SCD lost his mother whom was his confidant to complications of breast cancer when he was twelve year old. Therefore, another explanation of the co-morbidity in this adolescent might be that adjustment to SCD and other life stressors precipitated psychotic episodes in the course of ongoing schizophrenia.

Differential diagnosis and treatment response in this adolescent

This adolescent had experienced two episodes of acute and transient psychosis. The first episode at age fifteen lasted only three weeks and completely resolved as evidenced by the patient ability to re-focus on his academics and completing his high school education with good grades. This present episode which resolved following short duration of anti-psychotic medication had also been acute and transient, though the duration being longer than the first episode. The acute and transient nature of psychotic symptoms in this adolescent would point to a fleeting precipitating factor.

Conclusion

Putting into consideration the three possible dimensions of co-morbidity in this adolescent each of which pose its own treatment challenges, there is need for increased awareness and collaboration using the models of consultation and liaison services among psychiatrists and other health care professionals in managing children and adolescents with SCD.

Treating psychotic symptoms in this group of patients should be with caution regarding the choice of anti-psychotics. Anti-psychotic like Clozapine that had been documented to cause agranulocytosis should be avoided in these patients that are more predisposed to bacteria infections and aplastic anemia crises.

Iron overload among a psychiatric outpatient population.

J Clin Psychiatry. 1997 Feb;58(2):74-8.

Iron overload among a psychiatric outpatient population.

Abstract

BACKGROUND:

Iron overload has been suggested to be an unrecognized cause of psychiatric morbidity. This study sought to estimate the prevalence of iron overload in a large outpatient psychiatric clinic.

METHOD:

A retrospective review of screening blood chemistries was conducted on 661 active outpatients at a large, university outpatient psychiatric clinic to identify elevated iron status results (plasma iron, percentage of iron saturation) suggestive of iron overload. Patients with positive profiles were asked to undergo a subsequent blood chemistry to confirm positive results (plasma iron, percentage of iron saturation, plus plasma ferritin). Patients with positive repeated iron chemistry results were considered likely candidates for iron overload.

RESULTS:

Twenty-one patients (3.2%) were identified as meeting one of the criteria suggestive of iron overload on initial screening reports. Thirty-one percent of those who underwent subsequent, confirmatory testing (5/16) continued to meet one of the criteria. On the basis of these results, we estimated a 1% (3.2 x 0.31) prevalence rate of likely candidates for iron overload. A review of these patients’ charts indicated that they carried an unexpectedly high rate of bipolar affective disorder (80%) as a diagnosis and were, without exception, atypical in that they were resistant to conventional psychiatric treatment and lacked a family history for this disorder. The prevalence of positive iron overload profiles on a routine blood chemistry was similar to the prevalence of positive thyroid abnormalities based on TSH results in this population.

CONCLUSION:

Blood chemistry profiles suggestive of iron overload may be associated with a small portion of treatment-resistant psychiatric patients. Routine screening for iron abnormalities, especially in treatment-resistant patients, should be considered. Further studies are required to determine the causal association, if any, between iron excess and primary psychiatric illnesses.

Hereditary Hemochromatosis: Early Detection of a Common Yet Elusive Disease

Although widely regarded as a rare disorder, hereditary hemochromatosis is the most common genetic disease in Caucasians. In certain populations of northern European descent, 1 of every 200 persons is homozygous for the causative mutation.1

Hereditary hemochromatosis is also the most common cause of primary iron overload.

Schizophrenia-like psychosis and aceruloplasminemia

Abstract

Schizophrenia-like illnesses occur in a variety of medical and neurological conditions but to date have not been described in association with aceruloplasminemia. Aceruloplasminemia is an autosomal recessive disorder of iron metabolism which leads to iron deposition in the basal ganglia, thalamus, cerebellum and hippocampus and which usually presents in middle age with extrapyramidal symptoms and dementia. We describe a 21-year-old woman on treatment for aceruloplasminemia who presented with schizophrenia-like psychosis and declining function in the absence of neurological signs. Neuropsychological testing showed significant dominant hemisphere deficits. Magnetic resonance imaging showed bilateral iron deposition in the cerebellar dentate nuclei and thalami, frontal atrophy, and periventricular white matter hyperintensities. Functional imaging suggested global hypoperfusion. The clinical, cognitive and imaging findings were not typical for either aceruloplasminemia or schizophrenia alone and the possible relationship between the two disorders is discussed with particular reference to implications for our understanding of schizophrenia.

Heavy Metal: Iron and the Brain

Emily Deans M.D.

Iron deficiency is the most common nutritional problem in the world, affecting at least 2.5 billion people. In developing countries, as many as 40% of young children and 50% of pregnant women are deficient. Iron is a prevalent mineral, making up 5% of the earth’s crust, but a combination of inefficiency in absorption, poor iron in certain staple grain foods, and medical conditions make low iron levels a frequent occurrence among humans. Even in first world countries, iron is the most common nutrient deficiency.

Low iron intake and accelerated iron loss (generally through bleeding or breastfeeding) are the main causes of iron deficiency. Therefore pregnant women, breastfeeding women, women with heavy periods, children and other folks who are picky eaters, vegetarians and vegans, and anyone with digestion issues causing reduced absorption (such as celiac disease or post gastric bypass) or increased bleeding (such as cancer, ulcers, gastritis, or parasites) are at higher risk for iron deficiency. High intake of calcium (for example in kids who drink a ton of milk) can interfere with iron absorption as well, along with commonly used medications such as antacids and proton-pump inhibitors for gastroesophageal reflux disease.

While we are used to thinking of low iron levels as causing anemia due to red blood cells’ requirement for iron as a part of hemoglobin, iron is also desperately needed for the nerves and brain. Severe iron deficiency in young children can cause irreversible damage to cognition and result in lower IQ and developmental delays, particularly during a critical period of human development in utero and up to 16 months of age.

Even in adults the first symptoms of iron deficiency are often neurologic, as those affected will frequently complain of fatigue, brain fog, and also restless legs causing insomnia. Pica, the odd behavioral compulsion to eat nonnutritive foods such as dirt or clay, is extremely common in areas of the world where iron deficiency is prevalent. In the developed world, pica is rare but still occurs in children, pregnant women, and among other groups at higher risk for iron deficiency including those who have had gastric bypass. Non-neurologic symptoms of iron deficiency include pallor, generalized weakness, and higher than usual heart rate along with shortness of breath, particularly with exertion.
