Primary Autonomic Failure

	Primary Autonomic Failure Primary autonomic failure (also called primary dysautonomia) refers to a category of dysautonomias — conditions in which the autonomic nervous system does not function properly. In primary dysautonomias, the autonomic dysfunction occurs as a primary condition (as opposed to resulting from another disease). Autonomic failure is categorized as "primary" when believed to result from a chronic condition characterized by degeneration of the autonomic nervous system, or where autonomic failure is the predominant symptom and its cause is unknown. Such "primary" dysautonomias are distinguished from secondary dysautonomias, where the dysfunction of the autonomic nervous system is believed to be caused by another disease (e.g. diabetes). Diseases categorized as primary autonomic failure usually include pure autonomic failure and multiple system atrophy. Many scientists also categorize Parkinson disease Parkinson may refer to: Parkinson (surname) ''Parkinson'' (TV series), British ch ...

picture info	Dysautonomia Dysautonomia or autonomic dysfunction is a condition in which the autonomic nervous system (ANS) does not work properly. This may affect the functioning of the heart, bladder, intestines, sweat glands, pupils, and blood vessels. Dysautonomia has many causes, not all of which may be classified as neuropathic. A number of conditions can feature dysautonomia, such as Parkinson's disease, multiple system atrophy, dementia with Lewy bodies, Ehlers-Danlos syndromes, autoimmune autonomic ganglionopathy and autonomic neuropathy, HIV/AIDS, autonomic failure, and postural orthostatic tachycardia syndrome. The diagnosis is achieved through functional testing of the ANS, focusing on the affected organ system. Investigations may be performed to identify underlying disease processes that may have led to the development of symptoms or autonomic neuropathy. Symptomatic treatment is available for many symptoms associated with dysautonomia, and some disease processes can be directly treated. Sign ...

	Pure Autonomic Failure Pure autonomic failure (PAF) is a form of dysautonomia that first occurs in middle age or later in life; diagnosed more often in men than in women. Signs and symptoms A degenerative disease of the autonomic nervous system, symptoms include dizziness and fainting (caused by orthostatic hypotension), visual disturbances and neck pain. Chest pain, fatigue and sexual dysfunction are less common symptoms that may also occur. Symptoms are worse when standing; sometimes one may relieve symptoms by lying down. More pervasive autonomic dysfunction involving any of the following: night sweats or abnormal lack of sweating, urogenital problems (frequent UTIs, incontinence, frequency, urgency), gastrointestinal problems (chronic constipation, chronic constipation alternating with diarrhea, poor gastric motility), or esophageal/respiratory problems ( sleep apnea, abnormal breath sounds during sleep or while awake) indicate possible autoimmune autonomic ganglionopathy or multiple system at ...

	Multiple System Atrophy Multiple system atrophy (MSA) is a rare neurodegenerative disorder characterized by autonomic dysfunction, tremors, slow movement, muscle rigidity, and postural instability (collectively known as parkinsonism) and ataxia. This is caused by progressive degeneration of neurons in several parts of the brain including the basal ganglia, inferior olivary nucleus, and cerebellum. Many people affected by MSA experience dysfunction of the autonomic nervous system, which commonly manifests as orthostatic hypotension, impotence, loss of sweating, dry mouth and urinary retention and incontinence. Palsy of the vocal cords is an important and sometimes initial clinical manifestation of the disorder. A modified form of the alpha-synuclein protein within affected neurons may cause MSA. About 55% of MSA cases occur in men, with those affected first showing symptoms at the age of 50–60 years. MSA often presents with some of the same symptoms as Parkinson's disease. However, those with MSA gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
