Can seizures cause white matter lesions?
Can seizures cause white matter lesions?
MRI showed white-matter hyperintensities on both hemispheres with confluent lesions at the right parieto-occipital junction, with juxtacortical components. Such white matter lesions, close to the cortex, may be causative of seizures, like in multiple sclerosis.
Does the corpus callosum cause seizures?
A cut corpus callosum can’t send seizure signals from one side of the brain to the other. Seizures still occur on the side of the brain where they start. After surgery, these seizures tend to be less severe because they only affect half of the brain.
Does epilepsy affect white matter?
Overall, patients with epilepsy showed white matter abnormalities in the corpus callosum, cingulum, and external capsule, with differing severity across epilepsy syndromes.
Can seizures cause brain lesions?
CONCLUSION–Patients with seizures and abnormal imaging suggestive of structural lesions may occasionally have lesions that resolve spontaneously. While some diagnoses remain elusive, an important consideration to exclude in these patients is venous thrombosis.
What causes lesions in the white matter?
White matter lesions can be seen in a range of neurologic disorders, most often with vascular diseases such as stroke, migraine, and multiple sclerosis (MS).
Do seizures show up on MRI?
Does epilepsy show up on MRI scans? No, not necessarily. An MRI scan can help your doctor understand some of the possible underlying structural causes of your seizures. However, for many people there is no structural cause behind their epilepsy and so the brain scan comes back ‘normal’.
What happens when the corpus callosum is damaged?
Since each hemisphere controls the opposite side of the body, the brain must coordinate movements with both sides. This coordination is mediated by the corpus callosum. If the corpus callosum is damaged, then signals cannot pass from one hemisphere to the other. This can lead to serious coordination problems.
Is white matter the same as lesions?
Axons are surrounded by a fatty material called myelin, which insulates them like a sheath and gives white matter its color. Abnormalities in white matter, known as lesions, are most often seen as bright areas or spots on MRI scans of the brain. They can reflect normal aging; white matter deteriorates as people age.
What is white brain matter disease?
White matter disease is an umbrella term for damage to your brain’s white matter caused by reduced blood flow to the tissue. It can cause issues with memory, balance and mobility. People who have risk factors for cardiovascular disease also have a greater risk of developing white matter disease.
How are lesions and seizures related?
A lesion is a generic term for brain abnormalities that show up on imaging. Some types of lesions — such as cavernous malformations (blood vessel abnormality) and tumors — are prone to cause seizures.
What type of seizures are associated with brain tumors?
The type most commonly associated with brain tumours are called focal (or partial) seizures. Focal seizures affect only one part of the brain and can affect your movement and/or your level of consciousness or awareness. The symptoms you have will be different according to where the seizure starts in the brain.
