Lissencephaly (/ ˌ l ɪ s. ɛ n ˈ s ɛ f. ə l. i /, meaning 'smooth brain') [1] is a set of rare brain disorders whereby the whole or parts of the surface of the brain appear smooth. [2] It is caused by defective neuronal migration during the 12th to 24th weeks of gestation, resulting in a lack of development of brain folds and grooves . [3]
ECT is generally a second-line treatment for people with catatonia who do not respond to other treatments, but is a first-line treatment for severe or life-threatening catatonia. [ 4 ] [ 49 ] [ 50 ] There is a plethora of evidence for its efficacy, notwithstanding a lack of randomised controlled trials, such that "the excellent efficacy of ECT ...
Yellow softening is the third type of cerebral softening. As its name implies, the affected softened areas of the brain have a yellow appearance. This yellow appearance is due to atherosclerotic plaque build-up in interior brain arteries coupled with yellow lymph around the choroid plexus, which occurs in specific instances of brain trauma.

CES treatments have been found to induce changes in neurohormones and neurotransmitters that have been implicated in psychiatric disorders: substantial increases in beta endorphins, adrenocorticotrophic hormone, and serotonin; moderate increases in melatonin [7] [better source needed] and norepinephrine, modest or unquantified increases in ...
The condition is extremely rare — according to the Children's National Hospital, it only affects a handful of children a year — and the only way to diagnose it in utero is with an MRI.
The term 'pachygyria' does not directly relate to a specific malformation but rather is used to generally describe physical characteristics of the brain in association with several neuronal migration disorders; most commonly disorders relating to varied degrees of lissencephaly.
The diagnosis is usually made by a brain scan , in which areas of swelling can be identified. The treatment for PRES is supportive: removal of the cause or causes and treatment of any of the complications, such as anticonvulsants for seizures. PRES may be complicated by intracranial hemorrhage, but this is relatively rare. The majority of ...
Schilder disease or diffuse myelinoclastic sclerosis: is a rare disease that presents clinically as a pseudotumoural demyelinating lesion; and is more common in children. [56] [57] Solitary sclerosis: This variant was proposed (2012) by Mayo Clinic researchers. [58] though it was also reported by other groups more or less at the same time.
