The symptoms of an ataxia vary with the specific type and with the individual patient. Many subtypes of spinocerebellar ataxia result in cases where an individual retains full mental capacity but progressively loses physical control, but nearly half of the identified subtypes result in cognitive dysfunction, dementia, and mental retardation.

Subacute compression develops over days to weeks. Acute compression develops within minutes to hours. Acute compression may follow subacute and chronic compression, especially if the cause is abscess or tumor. Regardless of the pace, spinal cord compression will predictably progress over time.

When due to trauma, myelopathy is known as (acute) spinal cord injury. When inflammatory, it is known as myelitis. Disease that is vascular in nature is known as vascular myelopathy. In Asian populations, spinal cord compression often occurs due to a different, inflammatory process affecting the posterior longitudinal ligament. [citation needed]
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 prevention of dementia involves reducing the number of risk factors for the development of dementia, and is a global health priority needing a global response. [1] [2] Initiatives include the establishment of the International Research Network on Dementia Prevention (IRNDP) [3] which aims to link researchers in this field globally, and the establishment of the Global Dementia Observatory ...
This contributes to narrowing the spinal canal and compressing the spinal cord in the corresponding region. Herniated disk due to tearing of the spinal disk over time, causes the disk to protrude and exert pressure on surrounding spinal nerve tissue. Consequent compression on the spinal cord at the cervical region causes CSM. [12]
Anterior spinal artery syndrome is the most common form of spinal cord infarction. [1] The anterior spinal cord is at increased risk for infarction because it is supplied by the single anterior spinal artery and has little collateral circulation, unlike the posterior spinal cord which is supplied by two posterior spinal arteries.
Moderate-to-severe cases can cause radicular pain in the legs caused by nerve root compression. [5] The symptoms are usually exacerbated by upright posture and often, but not always, relieved by lying down. Postural headaches can be related to spontaneous spinal cerebrospinal fluid leaks. [6] However, in many patients, dural ectasia is ...
