Perisylvian syndrome is a rare neurological disease characterized by damage to the sylvian fissure (lateral sulcus), an area in the brain involved in language and speech. The main symptoms are difficulty chewing and swallowing, low muscle tone in the face and tongue, speech and language development disorders, and epilepsy.

What is Perisylvian aphasia?
Overview. The non-progressive perisylvian aphasias are common language disorders that follow focal, non-progressive cerebral cortical or subcortical injury to structures that occupy or adjoin the Sylvian fissure (areas supplied by the middle cerebral artery) most severely after damage to the left side of the brain.
What causes bilateral Perisylvian polymicrogyria?
Bilateral perisylvian polymicrogyria is a genetic disease, which means that it is caused by one or more genes not working correctly.

What causes Perisylvian syndrome?
Associated symptoms and findings are thought to be due to improper development of the outer surface of the brain (cerebral cortex) during embryonic growth (neuronal dysmigration). In most cases, the disorder appears to occur randomly for unknown reasons (sporadically).
Where is the Perisylvian area?
the area of the brain that is responsible for language. It consists of the region around the lateral sulcus (Sylvian fissure) of the left hemisphere and includes Broca's area and Wernicke's area. Damage to the zone causes various forms of aphasia.
Can you grow out of polymicrogyria?
Children with polymicrogyria will grow up to become adults with polymicrogyria. It cannot be outgrown. It is a lifelong disorder characterized by irreversible, abnormal brain development.
Is polymicrogyria a disability?
This condition causes severe intellectual disability, problems with movement, and seizures that are difficult or impossible to control with medication. Polymicrogyria most often occurs as an isolated feature, although it can occur with other brain abnormalities.
What is bilateral Perisylvian?
Overview. Bilateral perisylvian polymicrogyria (BPP) is a rare neurological disorder that affects the cerebral cortex (the outer surface of the brain). BPP is a subtype of a broader condition known as polymicrogyria. The cerebral cortex of the brain normally consists of several deep folds and grooves.

What is Pachygyria syndrome?
Pachygyria is a developmental condition due to abnormal migration of nerve cells (neurons) in the developing brain and nervous system.[1568] With pachygyria, there are few gyri (the ridges between the wrinkles in the brain), and they are usually broad and flat.
What is lissencephaly syndrome?
Lissencephaly, which literally means "smooth brain," is a rare, gene-linked brain malformation characterized by the absence of normal convolutions (folds) in the cerebral cortex and an abnormally small head (microcephaly). In the usual condition of lissencephaly, children usually have a normal sized head at birth.

What part of the brain is affected by anomic aphasia?
Anomic aphasia is typically caused by damage to the left hemisphere of the brain, the control center for speech and language. In some rare cases, anomia can be caused by damage to the right hemisphere of the brain.
What is non progressive aphasia?
Summary. Progressive non-fluent aphasia (PNFA) is a form of frontotemporal dementia (FTD; see this term), characterized by agrammatism, laborious speech, alexia, and agraphia, frequently accompanied by apraxia of speech (AOS). Language comprehension is relatively preserved.
What is Transcortical aphasia?
Transcortical sensory aphasia is an uncommon form of aphasia that may occur when a lesion functionally isolates Wernicke's areas from the rest of the brain, leaving the reception-to-output sufficiently unimpaired that repetition is preserved; neither speech comprehension nor spontaneous speech remain intact.

What causes bilateral perisylvian polymicrogyria?from rarediseases.info.nih.gov
In some cases, the cause may not be known. Genetic causes may include a contiguous gene disorder (a disorder caused by the deletion of multiple adjacent genes) or a single gene disorder (a disorder caused by a mutation in one gene). [4] BPP may also have non-genetic causes. It has been reported in association with complications in twin pregnancies, including twin–twin transfusion syndrome and intrauterine death of a co‐twin. It has additionally been reported in association with amniotic band syndrome. [6] [7]
