Neurology · Subcortical Band Heterotopia

Building Your Care Team

At a Glance

A coordinated care team for subcortical band heterotopia brings together an epilepsy specialist, genetics professionals, brain-imaging experts, therapists, and developmental or mental-health support. Bring MRI and EEG files, genetic reports, seizure records, and medication history to appointments.

Managing Subcortical Band Heterotopia (SBH) is too complex for any one doctor to handle alone. Because it affects the brain’s structure, electrical activity, and development, the standard of care involves a multidisciplinary team—a group of specialists who coordinate their expertise ^[1]^[2].

Essential Specialists for SBH

While many patients with well-controlled seizures can receive excellent ongoing care locally, referral to a Level 4 Comprehensive Epilepsy Center is particularly important for those with drug-resistant seizures, complex medication management needs, or those seeking presurgical evaluation ^[3]^[4].

Epileptologist: A neurologist who specializes specifically in epilepsy. They focus on choosing the right antiseizure medications and guiding complex treatment options ^[5]^[3].
Neurogeneticist & Genetic Counselor: Specialists who interpret genetic tests and provide individualized counseling on inheritance and recurrence risks ^[1]^[6].
Neuroradiologist: A doctor who specializes in reading brain images. In SBH, it is crucial to have a radiologist experienced in identifying subtle malformations of cortical development ^[7]^[6].
Neuropsychologist: These experts evaluate how the brain’s structure affects learning, memory, and behavior. Their evaluations are essential for guiding the school team in creating specialized education plans (IEPs) or workplace accommodations ^[6]^[8].
Rehabilitation Therapists: Physical (PT), Occupational (OT), and Speech therapists who work to maximize physical mobility, communication, and safe swallowing ^[9]^[2].
Broader Support: Developmental pediatricians, social workers, and mental-health professionals are critical for addressing behavioral health, navigating insurance, and supporting caregiver well-being.

Preparing for Appointments

Your intake at a specialized center is often a “deep dive” into the medical history. To make the most of this visit, you should bring the following items:

Imaging Data: Do not just bring the written report; bring the actual MRI files (DICOM format on a disc or USB) and complete EEG tracings/reports ^[6]^[5].
Genetic Reports: Bring the full laboratory report, which contains the specific variant codes needed for accurate counseling ^[10]^[11].
Seizure Records: A log of seizure types, their duration, missed doses, side effects, and any triggers. If you have videos of the seizures, these are incredibly helpful for doctors to see the semiology (what the seizure looks like) ^[5]^[10].
Medication History: A list of every medication tried, including the highest dose reached and exactly why it was stopped ^[12]^[10].

Evaluating Your Care Team

When meeting a new team, you are “interviewing” them as much as they are evaluating you. Consider asking:

“How many patients with SBH or lissencephaly-spectrum disorders does this center treat each year?” ^[1]
“Does this center have a dedicated ‘Epilepsy Surgery Conference’ where complex cases are reviewed by a whole team of experts?” ^[13]

A strong care team should not only treat the MRI findings but should also focus on your ability to participate in daily life, addressing mental health, transition planning, and the family’s overall well-being ^[5]^[14].

Common questions in this guide

Which specialists may be included in an SBH care team?

An SBH team may include an epileptologist, neurogeneticist or genetic counselor, neuroradiologist, neuropsychologist, and physical, occupational, and speech therapists. A developmental pediatrician, social worker, and mental-health professional may also help with development, school or work needs, insurance, and caregiver support.

When is a comprehensive epilepsy center especially helpful for SBH?

For people with drug-resistant seizures, complicated medication needs, or possible epilepsy surgery, a Level 4 Comprehensive Epilepsy Center can provide coordinated evaluation by multiple specialists. People whose seizures are well controlled may be able to receive ongoing care locally, depending on their needs.

What records should I bring to an SBH specialist appointment?

Bring the actual MRI files, preferably in DICOM format, along with complete EEG tracings or reports. Also bring the full genetic laboratory report, a seizure diary or videos, and a list of every antiseizure medicine tried, including the highest dose and why it was stopped.

Why do SBH specialists need the original MRI and EEG files?

Written reports summarize imaging and electrical tests, but reviewing the original files lets the team examine the brain structure and seizure activity directly. This can help them understand the visible band and assess which areas may be involved in the seizures.

How can an SBH care team support needs beyond seizure treatment?

Specialists can assess learning, memory, behavior, communication, movement, and swallowing, then help arrange therapies or school and workplace accommodations. Social workers and mental-health professionals can also help with insurance, community resources, emotional health, and caregiver well-being.

Curated prompts to bring to your next appointment.

1.Does this center have an epileptologist and neuroradiologist with specific experience in treating neuronal migration disorders like SBH?
2.Will the care team review the original MRI files and EEG tracings personally, rather than just reading the written reports?
3.How does the team distinguish between the visible 'double cortex' band and the actual areas of the brain that are causing the seizures?
4.What is the specific timeline and process for a formal 'drug-resistant epilepsy' evaluation if our current medications fail?
5.How will the team monitor and support non-medical needs, such as school/work accommodations, speech development, and behavioral health?
6.Can you connect us with a social worker or developmental pediatrician to help coordinate care and access community resources?

Key takeaways

SBH care is best coordinated by a multidisciplinary team that may include an epileptologist, genetics specialist, neuroradiologist, neuropsychologist, rehabilitation therapists, and support professionals.
A Level 4 Comprehensive Epilepsy Center is especially useful for drug-resistant seizures, complex medication needs, or presurgical evaluation.
Bring original MRI files, EEG tracings or reports, full genetic reports, seizure videos or a diary, and a complete medication history to specialist visits.
The team should address more than seizures, including learning, behavior, communication, mobility, swallowing, school or work accommodations, mental health, and caregiver well-being.
Choosing a primary point of contact can make it easier to coordinate appointments, records, treatment decisions, and community support.
