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 ...
Neurodegenerative diseases include amyotrophic lateral sclerosis, multiple sclerosis, Parkinson's disease, Alzheimer's disease, Huntington's disease, multiple system atrophy, tauopathies, and prion diseases. Neurodegeneration can be found in the brain at many different levels of neuronal circuitry, ranging from molecular to systemic. [4]
These abnormal cell types generate abnormal electrical signals which spread out to affect other parts of the cerebral cortex. Medication is used to treat the seizures that may arise due to cortical dysplasia. Epilepsy surgery to remove areas of FCD is a viable treatment option for appropriate candidates. [citation needed]
The impact of neurological disorders is profound and far-reaching. Conditions like epilepsy create recurring seizures through abnormal electrical brain activity, while multiple sclerosis damages the protective myelin covering of nerve fibers, interrupting communication between the brain and body.
Hippocampal sclerosis is the most common brain abnormality in those with temporal lobe epilepsy. [16] Hippocampal sclerosis may occur in children under 2 years of age with 1 instance seen as early as 6 months. [17] About 70% of those evaluated for temporal lobe epilepsy surgery have hippocampal sclerosis.
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 ...
Inflammatory demyelinating diseases (IDDs), sometimes called Idiopathic (IIDDs) due to the unknown etiology of some of them, are a heterogenous group of demyelinating diseases - conditions that cause damage to myelin, the protective sheath of nerve fibers - that occur against the background of an acute or chronic inflammatory process.
The typical demyelinating plaques in Schilder's sclerosis are usually found bilaterally in the centrum semiovale. Both hemispheres are almost completely occupied by large, well defined lesions. Although plaques of this kind are largely prevalent in Schilder's sclerosis, smaller lesions can also be observed. [citation needed]
