Thiamine and Alzheimer's disease. A pilot study.

Area of Science:

• Neuroscience
• Biochemistry
• Clinical Neurology

Background:

• Biochemical abnormalities in thiamine-dependent enzymes are noted in Alzheimer's disease.
• Thiamine deficiency can impact neurological function.

Purpose of the Study:

• To test the significance of biochemical abnormalities in thiamine-dependent enzymes in Alzheimer's disease.
• To evaluate the effects of oral thiamine hydrochloride on cognitive function in Alzheimer's disease patients.

Main Methods:

• A double-blind, placebo-controlled, crossover pilot study.
• Eleven moderately impaired probable Alzheimer's disease patients received 3 g/d of oral thiamine hydrochloride or niacinamide placebo for three months.
• Cognitive and behavioral ratings were assessed using the Mini-Mental State Examination.

Main Results:

• Global cognitive ratings, measured by the Mini-Mental State Examination, were higher with thiamine hydrochloride compared to placebo.
• No significant differences were observed in behavioral ratings or subjective clinical state.
• Patients were well-nourished and showed no signs of dietary thiamine deficiency.

Conclusions:

• Oral thiamine hydrochloride may improve global cognitive function in Alzheimer's disease patients.
• Further research is warranted to explore the therapeutic potential of thiamine in Alzheimer's disease.
• Thiamine's role in neurological health warrants continued investigation in neurodegenerative diseases.
