Final answer:
Donepezil, an Alzheimer's medication, can cause CNS adverse effects such as headache, dizziness, insomnia, and nausea. It may also lead to cognitive impairment, memory loss, and in severe cases, impaired coordination and balance.
Step-by-step explanation:
Adverse Effects of Donepezil on the CNS .The medication Donepezil, known under the brand name Aricept, is primarily used for the treatment of Alzheimer's disease and works by enhancing cholinergic function. While Donepezil is designed to improve cognitive function, it can have several adverse effects on the Central Nervous System (CNS). These adverse effects may include headache, dizziness, insomnia, and nausea. Beyond these, Donepezil may also cause cognitive impairment, memory lapses or loss, and impaired moral judgment. In more severe cases, patients may experience muscle weakness, impaired coordination and balance, and numbness, often described as "pins and needles" sensations. Symptoms such as severe yawning and hallucinations have been observed as well. It is crucial for patients and caregivers to monitor for these adverse effects and discuss them with a healthcare professional.
