bilateral frontoparietal polymicrogyria

Bilateral frontoparietal polymicrogyria (BFPP) is a rare neurological disorder that affects the cerebral cortex, specifically targeting the frontal and parietal lobes on both sides of the brain. This condition is characterized by an abnormal development of the brain before birth, resulting in an excessive number of small gyri and abnormal cortical lamination.

The symptoms of BFPP typically include moderate to severe intellectual disability, developmental delay, seizures, cerebellar ataxia, and other neurological abnormalities. The disorder is often associated with autosomal recessive inheritance, meaning that it is inherited in a pattern where a single copy of the mutated gene is enough to cause the condition.

BFPP can be caused by changes in the GPR56 gene, which plays a crucial role in brain development. However, the exact cause of the frontal form of polymicrogyria, including bilateral frontal polymicrogyria, remains unknown.

In terms of description, BFPP is a rare and complex neurological disorder that affects the brain's structure and function. It is characterized by an abnormal number of small gyri and cortical lamination, leading to severe intellectual disability, developmental delay, and other neurological symptoms.

Key features of bilateral frontoparietal polymicrogyria:

• Rare neurological disorder affecting the cerebral cortex
• Targets frontal and parietal lobes on both sides of the brain
• Abnormal development of the brain before birth
• Excessive number of small gyri and abnormal cortical lamination
• Symptoms include intellectual disability, developmental delay, seizures, cerebellar ataxia, and other neurological abnormalities

Bilateral frontoparietal polymicrogyria (BFPP) is a rare genetic disorder that affects the development of the brain's cerebral cortex, leading to various signs and symptoms.

Common Signs and Symptoms:

• Recurrent Seizures: Individuals with BFPP often experience recurrent seizures, which can range from mild to severe in intensity [1].
• Global Developmental Delay: People with this condition typically exhibit significant delays in reaching developmental milestones, such as walking, talking, and cognitive development [2].
• Crossed Eyes (Strabismus): Strabismus is a common feature of BFPP, where the eyes do not align properly, affecting vision and eye movement [1].
• Problems with Speech and Swallowing: Individuals with BFPP may experience difficulties with speech articulation, language development, and swallowing [2].
• Seizures and Epilepsy: Seizures are a hallmark symptom of BFPP, ranging from focal seizures to generalized tonic-clonic seizures [3].

Additional Symptoms:

• Atypical Absence Seizures: Some individuals may experience atypical absence seizures, characterized by brief periods of unresponsiveness [4].
• Tonic or Atonic Drop Attacks: People with BFPP may also experience sudden drops in muscle tone, leading to falls or loss of balance [4].
• Cerebellar Hypoplasia: In some cases, individuals with BFPP may exhibit cerebellar hypoplasia, a condition where the cerebellum is underdeveloped [5].

Bilateral frontoparietal polymicrogyria (BFPP) can be diagnosed through various diagnostic tests, which are essential for an accurate diagnosis and treatment plan.

• Brain Magnetic Resonance Imaging (MRI): This is the most reliable imaging modality for diagnosing BFPP. MRI scans show the abnormal brain structure and provide information on the location and extent of the polymicrogyria [5].
• Genetic Testing: Genetic testing can identify the underlying genetic cause of BFPP, such as mutations in the ADGRG1 gene [6]. This can be particularly useful for families with a history of the condition.
• Clinical Genetic Test: A clinical genetic test offered by Bioarray can also be used to diagnose BFPP. This test involves analyzing genes associated with the condition, including ADGRG1 [1].

It's worth noting that serum screening tests and other diagnostic tests may also be performed in some cases to rule out other conditions or identify any underlying chromosomal abnormalities [8]. However, high-resolution MRI remains the most reliable imaging modality for diagnosing BFPP.

Bilateral frontoparietal polymicrogyria (BFPP) is a rare brain condition characterized by the presence of multiple small gyri in the frontal and parietal regions of the brain. While there is no specific treatment to get rid of this condition, various medications can help control its symptoms.

Medications for Seizures

The first-line treatment for persons with seizures associated with BFPP is anti-seizure medications [2]. The medication chosen depends on the type of seizures or epilepsy syndrome. Treatment with anticonvulsant drugs may help prevent, reduce, or control various types of epilepsy associated with BFPP [8].

Other Medications

In addition to anti-seizure medications, other treatments may be necessary to manage symptoms such as delayed development or intellectual disability. While there is no specific medication for these symptoms, a multidisciplinary approach involving physical therapy, occupational therapy, and speech therapy can help improve overall functioning [9]. Anti-seizure drugs and orthotic devices may also be used to control seizures and improve mobility.

Bilateral frontoparietal polymicrogyria is a genetic disorder that causes a cortical malformation, leading to severe intellectual disability and other neurological problems [5]. When considering the differential diagnosis for this condition, several factors should be taken into account.

Key Features:

• Severe intellectual disability
• Global developmental delay of at least moderate severity
• Seizures (including focal seizures)
• Dysconjugate gaze
• Bilateral pyramidal and cerebellar signs

These features can help differentiate bilateral frontoparietal polymicrogyria from other conditions with similar symptoms.

Differential Diagnosis:

• Bilateral perisylvian polymicrogyria: This condition can cause facial and oromotor dysfunction, but it typically does not involve the same level of intellectual disability as bilateral frontoparietal polymicrogyria [10].
• Unilateral polymicrogyria: While unilateral forms of this disorder tend to be less severe than bilateral forms, they can still cause significant neurological problems. However, the symptoms may be more localized and less severe than those seen in bilateral frontoparietal polymicrogyria.
• Other genetic disorders: Conditions such as tuberous sclerosis complex or Aicardi syndrome can also present with seizures and intellectual disability. However, these conditions typically have distinct clinical features that differentiate them from bilateral frontoparietal polymicrogyria.

Diagnostic Clues:

• Focal cortical thickening is a key diagnostic clue for bilateral frontoparietal polymicrogyria [8].
• Signal intensity of the polymicrogyric cortex is similar to normal grey matter, which can aid in diagnosis [8].

In summary, when considering the differential diagnosis for bilateral frontoparietal polymicrogyria, it is essential to take into account the severity of intellectual disability, the presence of seizures and dysconjugate gaze, and the characteristic cortical malformation. By differentiating this condition from other genetic disorders and cortical malformations, a more accurate diagnosis can be made.
