Purpose of review: To critically review recent research in the development of non-pharmacological interventions to improve cognitive functioning in individuals with Alzheimer's disease (AD) or Parkinson's disease (PD).
Recent findings: Cognitive interventions can be grouped into three categories: cognitive stimulation (CS), cognitive training (CT), and cognitive rehabilitation (CR). CS confers temporary, nonspecific benefits and might slightly reduce dementia risk for neurologically healthy individuals. CT can improve discrete cognitive functions, but durability is limited and real-world utility is unclear. CR treatments are holistic and flexible and, therefore, most promising but are difficult to simulate and study under rigorous experimental conditions. Optimally effective CR is unlikely to be found in a single approach or treatment paradigm. Clinicians must be competent in a variety of interventions and select those interventions best tolerated by the patient and most relevant to their needs and goals. The progressive nature of neurodegenerative disease necessitates that treatment be consistent, open-ended in duration, and sufficiently dynamic to meet the patient's changing needs as their disease progresses.
