Differences between Tuberous Sclerosis Complex Patients with and without Epilepsy: The Results of a Quantitative...

Area of Science:

• Neuroimaging
• Neuroscience
• Medical Physics

Background:

• Tuberous sclerosis complex (TSC) is a genetic disorder affecting brain development.
• Epilepsy and cognitive deficits are common in TSC patients.
• Diffusion tensor imaging (DTI) is a key technique for studying white matter integrity.

Purpose of the Study:

• To investigate white matter microstructure differences in adult TSC patients with and without epilepsy.
• To compare DTI parameters between TSC patients and healthy controls.
• To identify specific white matter tract alterations associated with epilepsy in TSC.

Main Methods:

• Magnetic resonance imaging (MRI) with DTI sequence was used.
• 37 TSC patients (18 with epilepsy, 19 without) and 37 healthy controls participated.
• DTI parameters were analyzed across 20 white matter tracts.

Main Results:

• Significant DTI parameter differences were found between TSC patients with and without epilepsy.
• TSC patients with epilepsy showed abnormalities in 15/20 white matter tracts compared to controls.
• Epilepsy in TSC was linked to more extensive abnormalities in longer, left-hemisphere white matter tracts.

Conclusions:

• DTI can detect white matter changes in TSC.
• The presence of epilepsy in TSC is associated with distinct white matter microstructural alterations.
• Findings highlight the impact of epilepsy on brain integrity in TSC.
