Donepezil for Korsakoff Syndrome

Area of Science:

• Neuroscience
• Neurology

Background:

• Korsakoff syndrome is a severe neurocognitive disorder resulting from thiamine deficiency.
• It is characterized by memory impairment and confabulation.
• Wernicke's encephalopathy precedes Korsakoff syndrome and is reversible, but Korsakoff syndrome has limited treatment options.

Purpose of the Study:

• To investigate the potential benefits of donepezil in a patient with Korsakoff syndrome.
• To explore off-label therapeutic options for Korsakoff syndrome.

Main Methods:

• Case study based on clinical records and direct patient observations.
• Retrospective analysis of patient's response to donepezil treatment.

Main Results:

• The patient with Korsakoff syndrome showed improvement in cognition, motivation, and affect after initiating donepezil.
• Donepezil was well-tolerated in this case.

Conclusions:

• Off-label use of donepezil may be beneficial for managing symptoms of Korsakoff syndrome.
• Larger studies are required to confirm the safety and efficacy of donepezil for Korsakoff syndrome.
