The term "motor neuron disease" has varying meanings in different countries. Similarly, the literature inconsistently classifies which degenerative motor neuron disorders can be included under the umbrella term "motor neuron disease". The four main types of MND are marked (*) in the table below. [17] All types of MND can be differentiated by ...
Mitochondrial myopathies are diseases caused by mutations related to mitochondria, and thus are generally inherited from the mother with variable expressivity due to heteroplasmy. Kearns–Sayre syndrome; Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) Myoclonic epilepsy with ragged red fibers (MERRF)
ALS is the most common motor neuron disease in adults and the third most common neurodegenerative disease [61] after Alzheimer's disease and Parkinson's disease. [123] Worldwide the number of people who develop ALS yearly is estimated to be 1.9 people per 100,000 per year, while the number of people who have ALS at any given time is estimated ...

Conversely, a lower motor neuron lesion affects nerve fibers traveling from the anterior horn of the spinal cord or the cranial motor nuclei to the relevant muscle(s). [ 1 ] Upper motor neuron lesions occur in the brain or the spinal cord as the result of stroke , multiple sclerosis , traumatic brain injury , cerebral palsy , atypical ...
There is currently no known pharmacological treatment to hereditary motor and sensory neuropathy. However, the majority of people with these diseases are able to walk and be self-sufficient. [3] Some methods of relief for the disease include physical therapy, stretching, braces, and sometimes orthopedic surgery.

Distal hereditary motor neuronopathies (distal HMN, dHMN), sometimes also called distal hereditary motor neuropathies, are a genetically and clinically heterogeneous group of motor neuron diseases that result from genetic mutations in various genes and are characterized by degeneration and loss of motor neuron cells in the anterior horn of the spinal cord and subsequent muscle atrophy.
