In many cases, symptoms are mild enough to go unnoticed. The time period between episodes is known to vary between individuals. HNPP has not been found to alter the lifespan, although in some cases a decline in quality of life is noticed. Some sufferers (10–15%) report various pains growing in severity with progression of the disease. [1]
Progressive supranuclear palsy (PSP) is a late-onset neurodegenerative disease involving the gradual deterioration and death of specific volumes of the brain. [1] [2] The condition leads to symptoms including loss of balance, slowing of movement, difficulty moving the eyes, and cognitive impairment. [1]
Sural nerve biopsy; biopsy is considered for those patients in whom the diagnosis is not completely clear, when other causes of neuropathy (e.g., hereditary, vasculitic) cannot be excluded, or when profound axonal involvement is observed on EMG. Ultrasound of the peripheral nerves may show swelling of the affected nerves. [32] [33] [34]
Alzheimer's disease (AD) is a chronic neurodegenerative disease that results in the loss of neurons and synapses in the cerebral cortex and certain subcortical structures, resulting in gross atrophy of the temporal lobe, parietal lobe, and parts of the frontal cortex and cingulate gyrus. [14]
The average lifespan after the onset of symptoms in patients with MSA is 6–10 years. [4] Approximately 60% of patients require a wheelchair within five years of onset of the motor symptoms, and few patients survive beyond 12 years. [4] The disease progresses without remission at a variable rate.
Symptoms of motor neuron diseases can be first seen at birth or can come on slowly later in life. Most of these diseases worsen over time; while some, such as ALS, shorten one's life expectancy, others do not. [2] Currently, there are no approved treatments for the majority of motor neuron disorders, and care is mostly symptomatic. [2]
The initial presentation of PrP systemic amyloidosis is chronic diarrhea in the fourth decade of life, which may be misdiagnosed as Crohn's disease or irritable bowel syndrome. [1] Sensory and/or autonomic neuropathy follows. In one case, the disease caused optic nerve atrophy and visual disturbances in a Japanese woman. [2]
Neuroregeneration is the regrowth or repair of nervous tissues, cells or cell products. Neuroregenerative mechanisms may include generation of new neurons , glia , axons , myelin , or synapses . Neuroregeneration differs between the peripheral nervous system (PNS) and the central nervous system (CNS) by the functional mechanisms involved ...
