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 ...
Focal neurological deficits may be caused by a variety of medical conditions such as head trauma, [1] tumors or stroke; or by various diseases such as meningitis or encephalitis or as a side effect of certain medications such as those used in anesthesia. [2] Neurological soft signs are a group of non-focal neurologic signs. [3]
Limbic encephalitis refers to inflammatory disease confined to the limbic system of the brain. The clinical presentation often includes disorientation, disinhibition, memory loss, seizures, and behavioral anomalies. MRI imaging reveals T2 hyperintensity in the structures of the medial temporal lobes, and in some cases, other limbic structures ...
In other words, the symptoms of LATE are similar to those of Alzheimer's disease. The acronym LATE stands for L imbic-predominant A ge-related T DP-43 E ncephalopathy. “ Limbic ” is related to the brain areas first involved, “age-related” and the name “LATE” itself refer to the onset of disease usually in persons aged 80 or older.
Symptoms tend to present acutely over days to weeks. Its symptoms depend on which areas of the brain the disease affects, because specific parts of the brain have particular functions. [4] Many cases involve an attack on the limbic system, which includes structures like the amygdala, hippocampus, and thalamus. Respectively these brain regions ...
The default mode network has also been called the language network, semantic system, or limbic network. [11] Even though the dichotomy is misleading, [ 8 ] the term task-negative network is still sometimes used to contrast it against other more externally-oriented brain networks.
All the forms of psychosurgery in use today (or used in recent years) target the limbic system, which involves structures such as the amygdala, hippocampus, certain thalamic and hypothalamic nuclei, prefrontal and orbitofrontal cortex, and cingulate gyrus—all connected by fibre pathways and thought to play a part in the regulation of emotion.

Along with regions of the brains such as the limbic system, the dorsolateral prefrontal cortex deals heavily with major depressive disorder (MDD). The DLPFC may contribute to depression due to being involved with the disorder on an emotional level during the suppression stage. [ 39 ]
