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.
Multiple sclerosis can cause a variety of symptoms: changes in sensation (hypoesthesia), muscle weakness, abnormal muscle spasms, or difficulty moving; difficulties with coordination and balance; problems in speech or swallowing , visual problems (nystagmus, optic neuritis, phosphenes or diplopia), fatigue and acute or chronic pain syndromes ...
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]
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]
Often, the brain is able to compensate for some of this damage, due to an ability called neuroplasticity. MS symptoms develop as the cumulative result of multiple lesions in the brain and spinal cord. This is why symptoms can vary greatly between different individuals, depending on where their lesions occur.
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 ...
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).
