Brain degeneration also causes central nervous system diseases (i.e. Alzheimer's, Lewy body dementia, Parkinson's, and Huntington's diseases). Studies have shown that obese people may have severe degeneration in the brain [dubious – discuss] due to loss of tissue affecting cognition. [5] [citation needed]
Wallerian degeneration occurs after axonal injury in both the peripheral nervous system (PNS) and central nervous system (CNS). It occurs in the section of the axon distal to the site of injury and usually begins within 24–36 hours of a lesion. Prior to degeneration, the distal section of the axon tends to remain electrically excitable.
The nervous system is divided by neurologists into two parts: the central nervous system (which consists of the brain and spinal cord) and the peripheral nervous system (which consists of cranial and spinal nerves along with their associated ganglia). While the peripheral nervous system has an intrinsic ability for repair and regeneration, the ...
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
Autonomic nervous system disorders (e.g., dysautonomia, multiple system atrophy) Epilepsy; Movement disorders of the central and peripheral nervous system such as Parkinson's disease, essential tremor, amyotrophic lateral sclerosis (ALS), [failed verification] and Tourette syndrome [failed verification] Sleep disorders (e.g., narcolepsy)
Central pain syndrome, also known as central neuropathic pain, [1] is a neurological condition consisting of constant moderate to severe pain due to damage to the central nervous system (CNS) which causes a sensitization of the pain system. [2] [3] The extent of pain and the areas affected are related to the cause of the injury. [4]
Peripheral neuropathy may first be considered when an individual reports symptoms of numbness, tingling, and pain in feet. After ruling out a lesion in the central nervous system as a cause, a diagnosis may be made on the basis of symptoms, laboratory and additional testing, clinical history, and a detailed examination.
The peripheral nervous system (PNS) is one of two components that make up the nervous system of bilateral animals, with the other part being the central nervous system (CNS). The PNS consists of nerves and ganglia , which lie outside the brain and the spinal cord . [ 1 ]
