Introduction to Affective and Behavioral Changes The study of affective and behavioral changes constitutes a cornerstone of psychological science, psychiatry, and neuroscience. These changes refer to significant, measurable deviations from an individual’s established baseline in their emotional experience (affect) and their observable actions (behavior).

Understanding the behavioral effects of drinking […]
Introduction to Behavioral Phenotypes in Amyotrophic Lateral Sclerosis Amyotrophic Lateral Sclerosis (ALS) is traditionally understood as a devastating neurodegenerative condition characterized primarily by the progressive loss of motor neurons, leading to muscle weakness, atrophy, and eventual respiratory failure. However, contemporary research has decisively expanded this definition, recognizing that ALS exists along a spectrum of disease […]

Behavioral Symptoms of Dementia and Alzheimer’s Disease The complex pathology of dementia, particularly Alzheimer’s disease (AD), extends far beyond the well-known cognitive deficits such as memory loss and executive dysfunction. A significant and often debilitating component of these neurodegenerative disorders involves a wide spectrum of non-cognitive changes collectively termed Behavioral and Psychological Symptoms of Dementia […]
Introduction to Early Stage Dementia and Behavioral Changes The early stage of dementia, often characterized by Mild Cognitive Impairment (MCI) that progresses to clinical dementia, represents a critical period where subtle yet significant behavioral shifts begin to manifest. Unlike the typical forgetfulness associated with normal aging, these changes often involve alterations in personality, mood, and […]
Defining Behavioral and Psychological Symptoms of Dementia (BPSD) BPSD, often referred to as neuropsychiatric symptoms, encompasses a heterogeneous group of non-cognitive features that frequently occur in individuals suffering from various forms of dementia, including Alzheimer’s disease, vascular dementia, Lewy body dementia, and frontotemporal dementia. These symptoms represent a significant deviation from the individual’s premorbid functioning […]
