Disease Details
Family Health Simplified
- Description
- Bilateral parasagittal parieto-occipital polymicrogyria is a rare neurological disorder characterized by abnormal brain development, featuring multiple small and irregular folds in the cerebral cortex, predominantly in the parasagittal regions of the parieto-occipital areas on both sides of the brain.
- Type
- Bilateral parasagittal parieto-occipital polymicrogyria is a type of cortical development malformation characterized by abnormal folding of the brain's surface. The condition can exhibit various genetic transmission patterns, including autosomal recessive, autosomal dominant, and X-linked inheritance. Specific genetic mutations associated with the condition influence the mode of inheritance.
- Signs And Symptoms
-
Bilateral parasagittal parieto-occipital polymicrogyria (BPP-POP) is a type of brain malformation that affects the development of the cerebral cortex. The signs and symptoms can vary based on the extent and specific areas of the brain involved, but typically include:
1. **Developmental Delay:** Delays in reaching milestones such as sitting, walking, and talking.
2. **Intellectual Disability:** Ranging from mild to severe, affecting cognitive functions.
3. **Seizures:** Epileptic episodes which may be difficult to control.

5. **Speech and Language Problems:** Difficulties in producing and understanding speech.
6. **Feeding Difficulties:** Problems with chewing and swallowing can be present.
The exact presentation can differ from person to person, and in some cases, additional neurological or systemic symptoms may occur. - Prognosis
-
Polymicrogyria is a developmental brain malformation characterized by an excessive number of small and irregularly formed cerebral gyri. The prognosis for individuals with bilateral parasagittal parieto-occipital polymicrogyria can vary widely depending on the extent and severity of the malformation and associated symptoms.
- **Prognosis**: Individuals with this condition might experience varying degrees of cognitive and motor impairments, seizures, and developmental delays. The severity of these complications can range from mild to severe. Early intervention, supportive therapies, and tailored medical management can help improve quality of life.
It's important for affected individuals to have regular follow-ups with healthcare providers, including neurologists and specialists in developmental disorders. - Onset
- Bilateral parasagittal parieto-occipital polymicrogyria typically presents with onset in early childhood. This condition is a congenital malformation of the cerebral cortex characterized by an excessive number of small, irregular gyri. Symptoms can vary in severity and often include developmental delay, intellectual disability, and seizures.
- Prevalence
- Bilateral parasagittal parieto-occipital polymicrogyria (BPP-PO) is a very rare malformation of cortical development. Due to its rarity, precise prevalence data are not well-established. It is typically diagnosed through neuroimaging in individuals presenting with developmental delays, epilepsy, or other neurological symptoms.
- Epidemiology
- Bilateral parasagittal parieto-occipital polymicrogyria (BPP-PO) is a rare cortical malformation involving abnormal development of the brain's cerebral cortex. Epidemiological data specifically for BPP-PO are limited due to the rarity of the condition. Polymicrogyria, in general, has an estimated prevalence of 1 in 2,500 to 1 in 1,000 births, but the specific incidence of the bilateral parasagittal parieto-occipital variant is not well-documented in medical literature. The condition can be associated with genetic mutations, in-utero infections, or vascular insults during brain development. Diagnosis is typically confirmed through neuroimaging, particularly MRI.
- Intractability
- Bilateral parasagittal parieto-occipital polymicrogyria (BPP-PO) is often associated with challenging and intractable epilepsy, meaning that seizures may not respond well to conventional antiepileptic treatments. The condition may also lead to developmental delays and other neurological deficits. However, the severity and response to treatment can vary among individuals.
- Disease Severity
- Bilateral parasagittal parieto-occipital polymicrogyria is a neurological condition characterized by abnormal development of the brain's cerebral cortex. The severity of the disease can vary significantly. Some individuals may experience mild symptoms, while others could face severe intellectual disabilities, motor dysfunction, epilepsy, and other neurological issues. The specific impact depends on the extent and location of the abnormal brain development.

- Pathophysiology
-
Polymicrogyria is a malformation of cortical development characterized by an excessive number of small, unusually convoluted gyri on the surface of the brain. Specifically, bilateral parasagittal parieto-occipital polymicrogyria involves this abnormal cortical formation symmetrically in the parasagittal regions of the parietal and occipital lobes.
Pathophysiology:
- Prenatal Development: Polymicrogyria occurs due to disruptions in normal brain development during prenatal stages, typically between the 20th and 24th weeks of gestation.
- Cortical Malformation: The condition results from abnormal neuronal migration or post-migrational development. Neurons fail to form proper layers, leading to the brain's surface having excessive and disorganized folding.
- Genetic Factors: Various genetic mutations and environmental factors (such as infections, trauma, or ischemia during pregnancy) have been implicated in causing polymicrogyria.
The aberrant cortical organization affects neural communication, which can lead to a variety of neurological deficits depending on the specific brain regions involved. - Carrier Status
- Carrier status refers to whether an individual carries one copy of a gene mutation that, when present in two copies, causes a genetic disorder. For bilateral parasagittal parieto-occipital polymicrogyria, carrier status information is not typically specified as this condition can result from various genetic or environmental factors, and not necessarily from a single gene mutation passed in a simple carrier state.
- Mechanism
-
Bilateral parasagittal parieto-occipital polymicrogyria (BPP-POPMG) is a rare cortical malformation that affects brain development. Here's a concise explanation of its mechanism and potential molecular mechanisms:
### Mechanism:
1. **Structural Abnormality**: BPP-POPMG features abnormal development of the cerebral cortex, specifically in the parasagittal parieto-occipital regions. This malformation results in excessive folding of the cortical surface, leading to small, irregular gyri (polymicrogyria).
2. **Bilateral Symmetry**: The condition affects both sides of the brain symmetrically, which can influence motor, sensory, and cognitive functions depending on the severity and involved regions.
3. **Neurological Impact**: Symptoms can include intellectual disability, epilepsy, motor deficits, and speech and language impairments, which vary based on the extent of cortical involvement.
### Molecular Mechanisms:
1. **Genetic Mutations**: Genetic factors are often implicated. Mutations in specific genes such as ADGRG1 (formerly known as GPR56) and WDR62 have been associated with polymicrogyria. These genes play a role in the regulation of cortical development and neuronal migration.
2. **Neuronal Migration Disruption**: Proper cortical layer formation depends on the orderly migration of neurons. Disruption in signaling pathways (e.g., the reelin-signaling pathway) that guide neurons to their correct locations can result in polymicrogyria.
3. **Cell Adhesion Molecules**: Abnormal expression or function of cell adhesion molecules, which are essential for maintaining the structural integrity of cortical layers, may contribute to the abnormal folding patterns.
4. **Environmental Factors**: Although largely genetic, some environmental factors during pregnancy, such as infections or vascular insults, might interact with genetic predispositions to contribute to the development of BPP-POPMG.
Understanding of these mechanisms is crucial for diagnosing and potentially developing targeted treatments for individuals affected by this disorder. - Treatment

Currently, no specific repurposable drugs are widely recognized for the treatment of BPP-PO. Management primarily focuses on addressing symptoms, which may include seizures, developmental delays, and motor impairments. Seizures are often managed with antiepileptic drugs, and other symptoms are managed through supportive therapies such as physical and occupational therapy. Research into targeted treatments and potentially repurposable drugs is ongoing, but no definitive options exist as of now.
- Metabolites
-
Bilateral parasagittal parieto-occipital polymicrogyria (BPP-OP) is a congenital brain malformation characterized by excessive folding of the cerebral cortex and abnormal cortical layering. It typically affects the parietal and occipital lobes bilaterally. This condition can result in a range of neurological symptoms, including developmental delay, intellectual disability, epilepsy, and motor deficits.
Regarding metabolites, there is no specific set of metabolites uniquely associated with BPP-OP. However, metabolic studies and advanced neuroimaging techniques such as magnetic resonance spectroscopy (MRS) can sometimes reveal abnormalities in brain metabolism that might help in understanding and managing the disease. Typical findings might include changes in levels of N-acetylaspartate (NAA), choline, and creatine, which can indicate neuronal loss, altered membrane turnover, or altered energy metabolism respectively.
For more precise information on metabolites involved, genetic testing and detailed metabolic workups are usually required. - Nutraceuticals
-
Nutraceuticals are foods or food products that provide medical or health benefits, including the prevention and treatment of disease. However, for a specific condition like bilateral parasagittal parieto-occipital polymicrogyria (BPP), there is limited evidence to suggest that any particular nutraceuticals would directly impact the condition.
Bilateral parasagittal parieto-occipital polymicrogyria is a congenital malformation of the cerebral cortex, characterized by excessive folds in the brain, leading to neurological and developmental issues. Treatment usually focuses on managing symptoms such as seizures, developmental delays, and motor impairments. Nutritional support can play a role in overall patient health but is not a primary treatment for the structural brain anomalies observed in BPP.
If you are considering dietary supplements or nutraceuticals as part of a management plan, it is essential to consult with healthcare providers who can tailor advice to the specific needs of the individual affected by the condition. - Peptides
- Polymicrogyria is a cortical malformation characterized by an excessive number of small, malformed gyri on the surface of the brain. For bilateral parasagittal parieto-occipital polymicrogyria, peptides may not be the primary focus of treatment or research, as current understanding and management typically involve genetic studies, neuroimaging, and symptomatic treatments like seizure management and supportive therapies. As for nanotechnology, it is not currently a standard treatment approach for polymicrogyria, although ongoing research in nanomedicine may potentially offer future therapeutic options.
