Limbic encephalitis is caused by autoimmunity: an abnormal state where the body produces antibodies against itself. Some cases are associated with cancer and some are not. [1] Although the disease is known as "limbic" encephalitis, it is seldom limited to the limbic system and post-mortem studies usually show involvement of other parts of the ...
Autoimmune encephalitis (AIE) is a type of encephalitis, and one of the most common causes of noninfectious encephalitis. It can be triggered by tumors , infections , or it may be cryptogenic . The neurological manifestations can be either acute or subacute and usually develop within six weeks.
Patients typically have a fever [1] and may have seizures. The electrical activity of the brain changes as the disease progresses, first showing abnormalities in one temporal lobe of the brain, which spread to the other temporal lobe 7–10 days later. [1] Imaging by CT or MRI shows characteristic changes in the temporal lobes (see Figure).
Encephalitis with meningitis is known as meningoencephalitis, while encephalitis with involvement of the spinal cord is known as encephalomyelitis. [ 2 ] The word is from Ancient Greek ἐγκέφαλος , enképhalos 'brain', [ 37 ] composed of ἐν , en , 'in' and κεφαλή , kephalé , 'head', and the medical suffix -itis 'inflammation'.
Dysembryoplastic neuroepithelial tumour (DNT, DNET) is a type of brain tumor.Most commonly found in the temporal lobe, DNTs have been classified as benign tumours. [1] These are glioneuronal tumours comprising both glial and neuron cells and often have ties to focal cortical dysplasia.
Doctors will order an MRI to help diagnose cancer, brain injuries, damaged blood vessels and other medical conditions. Full-body scans can take an hour or more, with patients lying motionless ...
This is of particular importance in removing tumors and in patients who have intractable temporal lobe epilepsy. Lesioning tumors requires pre-surgical planning to ensure no functionally useful tissue is removed needlessly. Recovered depressed patients have shown altered fMRI activity in the cerebellum, and this may indicate a tendency to relapse.
Epstein-Barr virus encephalitis is usually accompanied by enlargement of the lymph nodes and enlargement of the spleen; Herpes zoster encephalitis may be accompanied by rash and skin vesicles, and because it involves the frontal lobe and temporal lobe, is often characterized by psychiatric features, memory deficits, and loss of language faculties.
