Both disciplines, cognitive neuropsychology and cognitive neuroscience, are involved in investigating the interaction between brain and behavior. In case of disease or damage of the brain, related changes are not necessarily observable with the help of brain or spinal cord imaging techniques. Abnormalities are rather displayed initially or exclusively in changes of behavior, cognition and/or the personality.
Cognitive and neuropsychiatric changes.
Frequent symptoms are:
- cognitive limitations in one or more domains (e.g. memory deficits, slowing in information processing speed, attentional problems)
- emotional instabilities (e.g. depressive mood, anxiety symptoms)
- changes or accentuations of personality traits (e.g. aggressiveness, neuroticism, disinhibition).
It has been known for decades that brain diseases can lead to cognitive and neuropsychiatric abnormalities, regardless of whether the disease was caused by inflammation, neurodegeneration or infection. Nevertheless, research on possible correlations and associated diagnostic and therapeutic consequences is still in its infancy.
