Factors associated with low cognitive performance in general practice

Area of Science:

• Neuroscience
• Gerontology
• Pharmacology

Background:

• Cognitive decline is a significant concern in aging populations.
• Understanding factors influencing cognitive function is crucial for early intervention.
• Longitudinal studies require careful consideration of medication effects.

Purpose of the Study:

• To investigate the association between antihypertensive medication, psychotropic drug use, and cognitive function in adults aged 45-75.
• To assess the impact of these medications on immediate recall, delayed memory, and attention.
• To inform the design of future longitudinal studies on cognitive aging.

Main Methods:

• A preparatory phase of a randomized controlled trial involving 1628 volunteers (age 45-75).
• Administration of a neuropsychological test battery assessing immediate recall, delayed memory, and attention.
• Analysis of cognitive test results in relation to antihypertensive medication and psychotropic drug use.

Main Results:

• Antihypertensive medication use was associated with lower scores on all cognitive tests across all age groups and blood pressure strata.
• Psychotropic drug use also correlated with lower cognitive test performance.
• The performance gap between psychotropic drug users and non-users widened with increasing age.

Conclusions:

• Antihypertensive treatment and psychotropic drug use are significant factors to consider in studies of cognitive decline in aging.
• These medications may influence cognitive function trajectories, necessitating their inclusion as covariates in research.
• Further research is warranted to explore the mechanisms behind these associations.
