This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
The classic triad of symptoms found in Wernicke encephalopathy is: [11] ophthalmoplegia (later expanded to other eye movement disorders, most commonly affecting the lateral rectus muscle. [11] Lateral nystagmus is most commonly seen although lateral rectus palsy, usually bilateral, may be seen). ataxia (later expanded to imbalance or any ...
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.
Note that the combination of AD+LATE is the most common and most severe. The term dementia refers to a clinical syndrome, rather than a particular disease process – it can be caused by many different subtypes of brain disease, which often occur in combination with each other. Thus, many different diseases including LATE contribute to dementia.
It is the most common neurodegenerative disease. [1] Even with billions of dollars being used to find a treatment for Alzheimer's disease, no effective treatments have been found. [15] Within clinical trials stable and effective AD therapeutic strategies have a 99.5% failure rate. [16]
Symptoms develop over days or weeks. The subacute development of short-term memory deficits is considered the hallmark of this disease, [1] but this symptom is often overlooked, because it is overshadowed by other more obvious symptoms such as headache, irritability, sleep disturbance, delusions, hallucinations, agitation, seizures and psychosis, or because the other symptoms mean the patient ...
Radiation optic neuropathy (RON) is also thought to be due to ischemia of the optic nerve that occurs 3 months to 8 or more years after radiation therapy to the brain and orbit. It occurs most often around 1.5 years after treatment and results in irreversible and severe vision loss, which may also be associated with damage to the retina ...
The MCA is the most common site for the occurrence of ischemic stroke. [1] Depending upon the location and severity of the occlusion, signs and symptoms may vary within the population affected with MCA syndrome. More distal blockages tend to produce milder deficits due to more extensive branching of the artery and less ischemic response.
