The subspecialty of Geriatric neurology is defined by its expertise in the diagnosis, treatment, and care of neurological conditions that affect elderly and by its unique body of knowledge regarding the aging nervous system, its vulnerability to specific neurological disorders, and its influence on the prevalence and expression of neurological ...
Roughly 20% of persons greater than 60 years of age have a neurological disorder, with episodic disorders being the most common followed by extrapyramidal movement disorders, and nerve disorders. [12] Diseases commonly associated with old age include Multiple system atrophy [13] Parkinson's disease [14] Alzheimer's disease [15] Stroke. [16]
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 ...
Many neurodegenerative diseases are caused by genetic mutations, most of which are located in completely unrelated genes. In many of the different diseases, the mutated gene has a common feature: a repeat of the CAG nucleotide triplet. CAG codes for the amino acid glutamine. A repeat of CAG results in a polyglutamine (polyQ) tract.
[2] [5] Rare genetic disorders that cause vascular lesions in the brain have other presentation patterns. As a rule, they tend to occur earlier in life and have a more aggressive course. In addition, infectious disorders, such as syphilis, can cause arterial damage, strokes, and bacterial inflammation of the brain. [10]
Brain degeneration also causes central nervous system diseases (i.e. Alzheimer's, Lewy body dementia, Parkinson's, and Huntington's diseases). Studies have shown that obese people may have severe degeneration in the brain [dubious – discuss] due to loss of tissue affecting cognition. [5] [citation needed]
Excitotoxicity occurs not only in AD, but also in other neurological diseases such as Parkinson's disease and multiple sclerosis. [186] Memantine is a noncompetitive NMDA receptor antagonist first used as an anti-influenza agent. It acts on the glutamatergic system by blocking NMDA receptors and inhibiting their overstimulation by glutamate.
Nervous system diseases, also known as nervous system or neurological disorders, refers to a small class of medical conditions affecting the nervous system.This category encompasses over 600 different conditions, including genetic disorders, infections, cancer, seizure disorders (such as epilepsy), conditions with a cardiovascular origin (such as stroke), congenital and developmental disorders ...
