#motor disorder
- Acromelalgia — A rare clinical syndrome characterized by paroxysmal episodes of intense burning pain, pronounced redness (erythema), and increased local temperature in the extremities (hands and feet). Symptoms are typically triggered by exposure to heat or physical exertion and are caused by a vasomotor disorder of the peripheral microcirculation.
- Acroneurosis — A general clinical term designating a group of functional neurological disorders, vasomotor and trophic in nature, localized exclusively within the extremities of the body (hands and feet). This structural neuromuscular manifestation includes syndromes such as Raynaud's disease, acrocyanosis, or erythromelalgia, characterized by crises of pallor, cyanosis, intense pain, paresthesias, and local changes in skin temperature, without an initial destructive organic lesion of the vessels.
- Allokinesia — A motor disorder of neurological origin consisting of the involuntary or reflex execution of a movement instead of the intended one, or the execution of a command by the symmetrical limb opposite to the one requested. This coordination dysfunction often occurs in hemineglect syndromes or following parietal lobe lesions, altering spatial perception and voluntary motor control.
- Angioneurosis — A well-defined dermatological or neurological disorder, characterized by paroxysmal vasomotor disturbances caused by an abnormal excitability of the vegetative nervous system regulating blood vessel caliber. This structural phenomenon manifests clinically through sudden vascular spasms or vasodilations, leading to local changes in skin color and temperature, circumscribed edemas, or ischemic-type pain, as observed in Raynaud's syndrome or Quincke's edema.
- Angiotrophoneurosis — A complex structural pathological state from the group of acroanesthesias and peripheral vasomotor disorders, characterized by the well-defined association of chronic spasms or vasodilations of small blood vessels with severe trophic changes in the innervated tissues. This process, caused by an abnormal excitability or functional degeneration of the neurovegetative nervous system, manifests clinically through paroxysmal painful episodes, cutaneous ulcerations, circumscribed edemas, and marked changes in the skin color of the extremities, as observed in Raynaud's disease or acrocyanosis.
