Spinal muscular atrophy (SMA) is a rare neuromuscular disorder that results in the loss of motor neurons and progressive muscle wasting. [ 3 ] [ 4 ] [ 5 ] It is usually diagnosed in infancy or early childhood and if left untreated it is the most common genetic cause of infant death. [ 6 ]
Autosomal recessive proximal spinal muscular atrophy, responsible for 90-95% of cases and usually called simply spinal muscular atrophy (SMA) – a disorder associated with a genetic mutation on the SMN1 gene on chromosome 5q (locus 5q13), diagnosed predominantly in young children and in its most severe form being the most common genetic cause ...
Cerebrospinal fluid (CSF) tests: Analysis of the fluid from around the brain and spinal cord could reveal signs of an infection or inflammation. [ 16 ] Magnetic resonance imaging (MRI): An MRI of the brain and spinal cord is recommended in patients with UMN signs and symptoms to explore other causes, such as a tumor, inflammation, or lack of ...
The supplementary motor area (SMA) is a part of the motor cortex of primates that contributes to the control of movement. It is located on the midline surface of the hemisphere just in front of (anterior to) the primary motor cortex leg representation. In monkeys, the SMA contains a rough map of the body. In humans, the body map is not apparent.
Spinal and bulbar muscular atrophy (SBMA), popularly known as Kennedy's disease, is a rare, adult-onset, X-linked recessive lower motor neuron disease caused by trinucleotide CAG repeat expansions in exon 1 of the androgen receptor (AR) gene, which results in both loss of AR function and toxic gain of function.
SMA projects directly to the spinal cord and may play some direct role in the control of movement. [37] Based on early work using brain imaging techniques in the human brain, Roland [38] suggested that the SMA was especially active during the internally generated plan to make a sequence of movements. In the monkey brain, neurons in the SMA are ...
Brain aneurysm causes: "Most aneurysms probably develop as a result of wear and tear on the arteries throughout a person's lifetime," the Brain Aneurysm Foundation noted . Some people can inherit ...
Congenital distal spinal muscular atrophy (cDSMA), also known as distal hereditary motor neuropathy (or neuronopathy) type VIII (dHMN8), is a hereditary medical condition characterized by muscle wasting (), particularly of distal muscles in legs and hands, and by early-onset contractures (permanent shortening of a muscle or joint) of the hip, knee, and ankle.
