DementiaCognitive declineMedical conditionDementia is a syndrome, classed as a major neurocognitive disorder often associated with neurodegenerative diseases such as Alzheimer's, and characterized by a general decline in cognitive processes that affects the ability to perform everyday activities. This typically involves problems with memory, thinking, behavior, and motor control.
DeliriumSevere confusion that develops quickly, and often fluctuates in intensityMedical conditionDelirium (formerly acute confusional state, an ambiguous term that is now discouraged) is a specific state of acute confusion attributable to the direct physiological consequence of a medical condition, effects of a psychoactive substance, or multiple causes, which usually develops over the course of hours to days.
Dementia with Lewy bodiesDementia with Lewy bodies (DLB) is a type of dementia characterized by changes in sleep, behavior, cognition, movement, and regulation of automatic bodily functions. Unlike some other dementias, memory loss may not be an early symptom. The disease worsens over time and is usually diagnosed when cognitive impairment interferes with normal daily functioning. Together with Parkinson's disease dementia, DLB is one of the two Lewy body dementias.
Alzheimer's diseaseProgressive neurodegenerative diseaseMedical conditionAlzheimer's disease (AD) is a neurodegenerative disease and is the most common cause of dementia, accounting for around 60–70% of cases. The most common early symptom is difficulty in remembering recent events. As the disease advances, symptoms can include problems with language, disorientation (including easily getting lost), mood swings, loss of motivation, self-neglect, and behavioral issues.
Huntington's diseaseInherited neurodegenerative disorderMedical conditionHuntington's or Huntington disease (HD), also known as Huntington's chorea, is a fatal neurodegenerative disease that is usually inherited. It typically presents as a triad of progressive psychiatric, cognitive, and motor symptoms. The earliest symptoms are often subtle problems with mood or mental/psychiatric abilities, which precede the motor symptoms for many people.
Social cognitionSocial cognition is a topic within psychology that focuses on how people process, store, and apply information about other people and social situations. It focuses on the role that cognitive processes play in social interactions. More technically, social cognition refers to how people deal with information about conspecifics (members of the same species) or even across species (such as pets), and includes four stages: encoding, storage, retrieval, and processing.
Mental disorderMedical conditionA mental disorder, also referred to as a mental illness, a mental health condition, or a psychiatric disability, is a behavioral or mental pattern that causes significant distress or impairment of personal functioning. A mental disorder is also characterized by a clinically significant disturbance in an individual's cognition, emotional regulation, or behavior, often in a social context.
DSM-5The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), is the 2013 update to the Diagnostic and Statistical Manual of Mental Disorders, the taxonomic and diagnostic tool published by the American Psychiatric Association (APA). In 2022, a revised version (DSM-5-TR) was published. In the United States, the DSM serves as the principal authority for psychiatric diagnoses.Cognitive skillCognitive skills are skills of the mind, as opposed to other types of skills such as motor skills, social skills or life skills. Cognitive skills include literacy, self-reflection, logical reasoning, abstract thinking, critical thinking, introspection and mental arithmetic.
Frontotemporal dementiaDementia involving the frontal or temporal lobesMedical conditionFrontotemporal dementia (FTD), also known as frontotemporal degeneration, and historically as Pick's disease, is a family of neurodegenerative disorders, caused by frontotemporal lobar degeneration that affects the frontal and temporal lobes.
Executive functionsCognitive processes necessary for control of behaviorIn cognitive science and neuropsychology, executive functions (collectively referred to as executive function and cognitive control) are a set of cognitive processes that support goal-directed behavior, by regulating thoughts and actions through cognitive control, selecting and successfully monitoring actions that facilitate the attainment of chosen objectives.
