Balance and sleep quality are significantly associated with attentional processing in Parkinson's disease, as measured by P300 latency
In a cross-sectional study of 28 individuals with Parkinson's disease and 27 healthy controls, balance (B = -4.909, P = 0.001) and sleep quality (B = 12.704, P = 0.007) were significantly associated with P300 latency, indicating their relevance to attention. Depression was not significantly associated with P300 latency (B = 3.472, P = 0.084).

The Claim
Balance and sleep quality are significantly associated with attentional processing in Parkinson's disease, as measured by P300 latency
This conclusion is most relevant to: 28 individuals with Parkinson's disease and 27 healthy controls.
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Assessment of balance, sleep quality, and depression in relation to attention in Parkinson's disease: A cross-sectional P300 study. (Sao Paulo medical journal = Revista paulista de medicina, 2026) —
How It Works
The proposed biological pathway:
- ▸Parkinson's disease involves neurodegeneration affecting motor and non-motor functions
- ▸Balance deficits and poor sleep quality may impair cognitive processing resources
- ▸P300 latency reflects attention and discrimination processes
- ▸Result: Balance and sleep quality are significantly associated with attentional processing in PD
Who Might Benefit
Evidence fit by population:
- ▸28 individuals with Parkinson's disease and 27 healthy controls
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Cross-sectional design prevents causal inference
- ▸Small sample size (28 PD patients) limits generalizability
Frequently Asked Questions
What is P300 latency and why is it used to measure attention?▼
P300 latency is an auditory event-related potential that reflects the speed of neural processing related to attention and discrimination. It is a sensitive indicator of attentional deficits in neurological conditions like Parkinson's disease.
How was balance assessed in this study?▼
Balance was assessed using the Berg Balance Scale (BBS), a clinical test that evaluates functional balance through tasks like standing, reaching, and turning.
Did depression significantly affect attention in Parkinson's disease patients?▼
No, depression as measured by the Beck Depression Inventory was not significantly associated with P300 latency (B = 3.472, P = 0.084), suggesting it may not independently impact attentional processing in this sample.
What are the clinical implications of this study?▼
The findings suggest that balance training and improving sleep quality may be relevant targets for managing attention deficits in Parkinson's disease, though further research is needed.
