This mutant protein causes degradation in certain types of neurons, like Purkinje neurons, which are common in the cerebellum, spinal cord, and related parts of the brain. While the mechanism is not fully understood, it is suspected that changes in the interactions between ataxin 1 and other proteins result in a toxic gain of function.
In an effort to understand the cause of cataracts—beyond the normal wear-and-tear of aging, smoking, and exposure to UV rays, all of which can damage a lens’ fiber cells—researchers are ...
Posterior capsular opacification, also known as after-cataract, is a condition in which months or years after successful cataract surgery, vision deteriorates or problems with glare and light scattering recur, usually due to thickening of the back or posterior capsule surrounding the implanted lens, so-called 'posterior lens capsule opacification'.
Tabes dorsalis is a late consequence of neurosyphilis, characterized by the slow degeneration (specifically, demyelination) of the neural tracts primarily in the dorsal root ganglia of the spinal cord (nerve root). These patients have lancinating nerve root pain which is aggravated by coughing, and features of sensory ataxia with ocular ...
The specific causes of neurological problems vary but can include genetic disorders, congenital abnormalities or disorders, infections, lifestyle, or environmental health problems such as pollution, malnutrition, brain damage, spinal cord injury, nerve injury, or gluten sensitivity (with or without intestinal damage or digestive symptoms).
The first ataxia gene was identified in 1993 and called "Spinocerebellar ataxia type 1" (SCA1); later genes were called SCA2, SCA3, etc. Usually, the "type" number of "SCA" refers to the order in which the gene was found. At this time, there are at least 49 different gene mutations that have been found. [citation needed]
A neurological disease refers to any ailment of the central nervous system, including abnormalities of the brain, spinal cord and other connecting nerve fibres. [8] Where millions of people are affected by neurological diseases on a worldwide scale, [8] it has been identified that the number of different types of neurological diseases exceeds six hundred, [9] any of which an individual can incur.
Congenital conditions and tumors that compress the cord can also cause SCI, as can vertebral spondylosis and ischemia. [5] Multiple sclerosis is a disease that can damage the spinal cord, as can infectious or inflammatory conditions such as tuberculosis, herpes zoster or herpes simplex, meningitis, myelitis, and syphilis.
