title: [Psychopathology of stroke].
abstract: The psychopathology of stroke encompasses several psychiatric and behavioral disorders that have high prevalence in the geriatric population, reduce the patient autonomy and increase the caregiver's burden. These disorders are usually associated with other cognitive and neurological deficits, and are labelled as neuropsychiatric when the whole clinical picture is consistent with the specific dysfunction of a neural system or brain region. Thus the neuropsychiatry of stroke comprises disorders of the perception/identification of the self and the environment (anosognosia of hemiplegia, misidentification syndromes, confabulations, visual hallucinations, delirium and acute confusional state), amotivational syndromes (apathy and athymhormia), disorders of emotional reactivity (blunted affect, emotional incontinence, irritability, catastrophic reactions), poor impulse or ideation control (mania) and personality changes. The clinical profile of the subcortical vascular dementia also points to specific brain dysfunction (frontal-subcortical pathways) that manifests with behavioral (depression, emotionalism, irritability) and cognitive symptoms (psychomotor retardation, attention, executive and memory deficits). However, post-stroke depression and anxiety, which have a more variable clinical presentation and might be assimilated, for several aspects, to post-traumatic or adaptive disorders, are disorders less characterized in their neural correlates.
