Definition The transient ischemic attack - also known by the acronym TIA - is a particular form of ischemic attack, which causes a temporary and reversible neurological deficit (unlike what happens in the stroke where the consequences are permanent). Causes The transient ischemic attack is caused by a reduced blood supply to a certain area of ​​the brain. Th

Definition Potentially debilitating, multiple sclerosis is an autoimmune disease that involves the nervous system; the altered immune system, directed against the protective myelin coating of the nerves, hinders the correct communication between the brain and the other parts of the body. The disease, irreversible, can arise at any age, but tends to prefer women of a young and adult age

Generality The nerves are important structures of the peripheral nervous system, which result from the grouping of several axons and which have the important task of transporting nerve impulses from the central nervous system to the periphery, and vice versa. In the human body, there are two types of nerves: cranial nerves and spinal nerves

Generality The nervous system receives the different stimuli coming from the inside and from the outside of the body, analyzes them, processes them and generates appropriate responses to favor the survival of the organism itself. The vertebrate nervous system comprises two components: Central Nervous System (CNS): receives and analyzes information coming from the internal and external environment of the organism, then processes the most appropriate answers; Peripheral Nervous System (SNP): captures the stimuli coming both from the external environment and from inside the body, then transmits th

Encephalopathies represent a group of particular pathologies, which are distinguished by a structural and functional alteration of the brain. The various types of encephalopathy differ from each other due to the triggering causes - to which they usually owe their names - for the symptoms, for the complications, for the treatment and for the prognosis

Attention deficit hyperactivity disorder ( ADHD ) is a neuropsychic disorder, typical of childhood and adolescence , which includes a wide range of symptoms. In fact, those suffering from it experience difficulty (or declines) in concentration , hyperactivity , restlessness , extreme impulsiveness , unusual aggressiveness , mood disorders, sleep disorders, anxiety, depression, stress and other similar problems

The third most common form of dementia in the world (after Alzheimer's disease and vascular dementia), dementia with Lewy bodies is a neurodegenerative disorder of the brain, which causes a progressive decline of a person's cognitive faculties . Its particular name is linked to the fact that, inside the neurons of the encephalic areas subject to neurodegeneration, insoluble protein aggregates containing alpha-synuclein and called Lewy bodies are formed

Frontotemporal dementia is a neurodegenerative disorder of the brain, which arises due to the progressive deterioration of neurons located at the level of the frontal and temporal lobes of the brain proper . With repercussions on language, behavior, ability to think and part of the movements, frontotemporal dementia was once called Pick's disease , in honor of Arnold Pick, who described it for the first time in 1892

In medicine, the term dementia indicates a neurodegenerative disease of the brain, typical of the advanced age (but not exclusive to the elderly), which involves the gradual and almost always irreversible reduction of the intellectual faculties (capacity of thought, memory, language and behavior, etc
