Abstract: Tay-Sachs disease (a GM2 gangliosidosis) is an inherited neuronal storage disease that can affect individuals across the age spectrum.
Psychosis is reported in 30% to 50% of adult-onset patients, and many are misdiagnosed with schizophrenia.
Mood disorders are present in more than 25% and cognitive impairment in more than 20%.
Treatment of psychosis with neuroleptics may not have a favorable risk/benefit ratio, but treatment with benzodiazepines or electroconvulsive therapy may be efficacious.
Metabolic diseases such as gangliosidosis are probably under-recognized as causes of neuropsychiatric illness.
Increased awareness of these disorders will lead to accurate diagnosis, appropriate treatment selection, and genetic counseling. PMID: 9547461 [PubMed – indexed for MEDLINE]
