Distorted time perception in patients with neurocognitive impairment

Area of Science:

• Neuroscience
• Psychology
• Gerontology

Background:

• Time perception is altered in neuropsychiatric disorders.
• Neurocognitive impairment affects temporal processing.
• Investigating time distortion in Alzheimer's disease, vascular dementia, and Parkinson's disease dementia is crucial.

Purpose of the Study:

• To explore the correlation between cognitive decline and time distortion.
• To compare time perception in neurocognitive impairment versus subjective cognitive impairment.
• To assess temporal abilities in Alzheimer's disease, vascular dementia, and Parkinson's disease dementia patients.

Main Methods:

• 569 participants with cognitive decline complaints were studied.
• Utilized verbal estimation, time production, and time comparison tasks.
• Neuropsychological assessments were conducted alongside temporal tasks.

Main Results:

• Neurocognitive impairment patients exhibited distorted time perception compared to SCI.
• Vascular dementia patients showed the lowest MMSE scores and greatest time-estimation errors.
• Vascular dementia patients significantly underestimated time and performed poorly in time comparison tasks.

Conclusions:

• Vascular dementia patients demonstrate the most impaired time perception.
• Findings suggest a link between cognitive functions and temporal perception abilities.
• This research contributes to understanding the pathophysiology of temporal processing deficits.
