Objective. The main hypothesis was that subtle vitamin B12 deยฎciencies occur more commonly in senile dementia of Alzheimer type (SDAT) than in healthy elderly individuals, and may be revealed by elevated total serum homocysteine (tHcy). A subsidiary hypothesis was that such deยฎciencies would be nutr

โฆ Synopsis
Acetylcholinesterase (AChE) activity was measured in cerebrospinal fluid (CSF) samples from 36 individuals, including 12 persons with Alzheimer's disease, 12 normal controls, and 12 patients with other dementias. AChE activity also was measured in 47 normal subjects whose ages ranged from 20 to 84 to evaluate the effect of age on AChE activity. CSF from patients with senile dementia of the Alzheimer type showed significantly lower mean AChE activity than in age-matched controls and patients with other dementia syndromes. No correlation was found between duration of illness, age, or severity of illness (as measured by the Mini-Mental State Examination score) and CSF AChE activity in Alzheimer's disease. AChE increased significantly over the age range of 20 to 84. CSF AChE activity may prove to be a useful diagnostic test to confirm the clinical diagnosis of moderate to severe Alzheimer's disease.

## Abstract Sixtyโsix subjects diagnosed by validated criteria as having senile dementia of the Alzheimer type (SDAT) were assessed with clinical measures commonly used to study dementia. The severity of the SDAT was mild in 24, moderate in 24, and severe in 18. The data from these three groups in
Monoamine metabolites, biopterin, acetylcholinesterase (AChE) activity, and somatostatin-like immunoreactivity (SLI) were determined in the lumbar cerebrospinal fluid (CSF) of 24 patients with dementia of the Alzheimer type (DAT) without myoclonus or extrapyramidal signs, in 8 patients with DAT and
