'''Pachygyria''' is a congenital (present from birth) malformation of the cerebral cortex, the part of the brain that plays a key role in memory, attention, perceptual awareness, thought, language, and consciousness. It involves the brain's cerebral cortex having fewer and thicker folds than normal. Pachygyria is also known as "macrogyria". It is a type of cortical dysplasia, and is often associated with [[lissencephaly]]. | '''Pachygyria''' is a congenital (present from birth) malformation of the cerebral cortex, the part of the brain that plays a key role in memory, attention, perceptual awareness, thought, language, and consciousness.

Pachygyria is a congenital (present from birth) malformation of the cerebral cortex, the part of the brain that plays a key role in memory, attention, perceptual awareness, thought, language, and consciousness. It involves the brain's cerebral cortex having fewer and thicker folds than normal. Pachygyria is also known as "macrogyria". It is a type of cortical dysplasia, and is often associated with lissencephaly.
Causes[edit]
Pachygyria is caused by abnormal migration of nerve cells (neurons) in the developing brain and nervous system. With pachygyria, there are few gyri (the ridges between the wrinkles in the brain), and they are usually broader and less well formed than usual. The condition is usually the result of genetic mutations. It is often seen in conditions such as Zellweger syndrome, Aicardi syndrome, and Neuronal migration disorders.
Symptoms[edit]
Symptoms of pachygyria can vary greatly, but often include poor muscle tone, motor delays, seizures, failure to thrive, difficulties with the coordination of movements, and intellectual disability. The symptoms of pachygyria are generally noticed in infancy and may include developmental delay, seizures, poor muscle control, feeding difficulties, and stiffness caused by abnormal tenseness of muscles (spasticity).
Diagnosis[edit]
Diagnosis of pachygyria is usually made through imaging studies, such as MRI, which can reveal the characteristic abnormalities in the brain's structure. Genetic testing may also be used to identify the underlying genetic cause.
Treatment[edit]
There is no cure for pachygyria. Treatment is symptomatic and supportive. It may include physical therapy to improve motor skills, anticonvulsant medications to control seizures, and special education programs to address developmental delays.
Prognosis[edit]
The prognosis for individuals with pachygyria varies depending on the severity of brain malformations. Some individuals may have a normal life span with near-normal intelligence, while others may be severely disabled. Seizures can be difficult to control, and may further impact quality of life.
