Feasibility of a cognitive strategy training intervention for people with Parkinson's disease.

This was a small case series of only seven participants, so it cannot determine if the intervention is effective. All participants were highly educated, had high socioeconomic status, and were motivated, which may limit generalizability to patients with different backgrounds or less insight. A single therapist delivered all interventions, and some feasibility measures were completed with the therapist present, which could bias satisfaction ratings. The study did not have a control group, so improvements cannot be attributed solely to the intervention. One participant dropped out after pre-testing, and the sample included only people with subjective cognitive decline, not those with diagnosed mild cognitive impairment or dementia.

The authors report no conflicts of interest.

Do not conclude that this intervention improves cognitive function or daily performance. The study was designed only to test feasibility and acceptability. The reported improvements in self-reported performance were exploratory and occurred in a very small, highly selected group of motivated participants without a control group, so they cannot be interpreted as evidence of efficacy.
