Behaviour changes in dementia. 1: Point of entry data of a prospective study

Area of Science:

• Neurology
• Gerontology
• Psychiatry

Background:

• Dementia diagnosis and management require understanding behavioral changes.
• Longitudinal studies are crucial for tracking dementia progression and its impact.

Purpose of the Study:

• To analyze behavior changes in dementia patients at the beginning of a longitudinal study.
• To identify correlations between behavior, cognitive impairment, and demographic factors.

Main Methods:

• Prospective, longitudinal study involving 97 participants with dementia (Alzheimer's and/or vascular dementia) living at home.
• Carer interviews and cognitive assessments conducted at 4-month intervals.
• Behavior assessed using the reliable Present Behavioural Examination (PBE).

Main Results:

• Behavioral changes were analyzed at study entry.
• Few correlations found between behavior and age, gender, or time since dementia onset.
• Increased prevalence of certain behaviors correlated with greater cognitive impairment.

Conclusions:

• Behavioral changes like aggression, wandering, and nighttime wakefulness are prevalent and problematic for caregivers.
• These challenging behaviors are generally more common in individuals with more severe dementia.
