Cerebellar Cognitive Affective Syndrome (CCAS) is a rare neurological disorder that affects the cerebellum, the part of the brain responsible for motor control, coordination, and balance. The syndrome can cause a range of symptoms, including difficulty with memory, executive functions, emotion regulation, and language processing. There are several different synonyms for CCAS, including Cerebellar Cognitive Affective Disorder (CCAD), Cerebellar Cognitive Syndrome (CCS), and Cerebellar Ataxia with Cognitive Impairment (CACI). These terms are often used interchangeably and refer to the same set of symptoms and functional impairments associated with the syndrome. While CCAS is not curable, early diagnosis and interventions can help manage the symptoms and improve the patient's quality of life.
