A study in Clinical Therapeutics (1992 May;14(3):426-437) showed that the intravenous administration of large doses of methylcobalamin to Alzheimer’s patients improved the patients’ intellectual functions such as memory, emotions and communication with other people. The scientists concluded that methylcobalamin is a safe and effective treatment for psychiatric disorders in patients with Alzheimer-type dementia.
This is the only clinical study the Foundation could find on using methylcobalamin to treat Alzheimer’s disease. It could be that 40 to 80 mg a day of sublingually administered methylcobalamin would be an effective adjuvant (assisting) Alzheimer’s therapy.
