Objective: To study the efficacy of cognitive rehabilitation combined with acetylcholinesterase inhibitor (AChE-I) treatment in patients with mild Alzheimer's disease and their relatives.
Method: Thirteen patients with mild Alzheimer's disease treated with rivastigmine 6-12 mg/day for more than two months started cognitive rehabilitation training. Before and after the cognitive rehabilitation training patients were assessed through cognitive tests, activities of daily living scale, neuropsychological battery and scales to evaluate caregivers' depressive and anxiety symptoms. Six patients were randomized to a combined treatment group (AChE-I plus cognitive rehabilitation and caregiver support) and seven patients to a control group (AChE-I only) and followed up for five months.
Results: Mini-Mental State Examination (MMSE) scores (p=0.047) and backward digit span scores (p=0.018) were significantly different between the groups on follow-up. The combined treatment group showed a better positive treatment effect on cognitive and neuropsychological tests applied to patients and reduction of psychiatric symptoms was observed in their caregivers (nonsignificant).
Conclusion: Cognitive rehabilitation associated with AChE-I treatment can potentially be useful to stabilize or improve cognitive and functional performance of patients with mild Alzheimer's disease and can reduce caregivers' psychiatric symptoms.
