Generalized Seizures
What is it?
Generalized seizures involve both sides of the brain and typically affect consciousness. These seizures can be classified into several types, including tonic-clonic seizures (formerly known as grand mal) and absence seizures (formerly known as petit mal).
Who is affected?
Generalized seizures can affect people of all ages, but they are often first diagnosed in childhood or adolescence. Some individuals may experience generalized seizures as part of epilepsy, while others may have them due to factors like brain injury or infections.
Diagnosis:
The diagnosis is confirmed through an electroencephalogram (EEG) which records electrical activity in the brain. Medical history, neurological exams, and imaging tests like MRI or CT scans are also used to determine the underlying cause.
Symptoms:
- Sudden loss of consciousness
- Muscle stiffening (tonic phase)
- Jerking movements (clonic phase)
- Brief episodes of staring or loss of awareness (absence seizures)
- Uncontrolled movements or speech difficulties
Treatment:
Treatment involves anticonvulsant medications, such as valproate, lamotrigine, or levetiracetam, to prevent seizure episodes. Lifestyle changes, including adequate sleep and stress management, are also essential in controlling the condition.
Doctor Selection:
A neurologist, particularly one specialized in epilepsy, is crucial for diagnosis and long-term management. An epileptologist (epilepsy specialist) is often recommended for more complicated cases.
Precautions:
- Avoiding triggers such as sleep deprivation or flashing lights.
- Medication adherence to maintain stable brain activity.
Role of Family:
Family members should ensure the patient’s safety during a seizure, such as preventing falls or injuries. They should also assist with medication adherence and provide emotional support.
Focal Seizures
What is it?
Focal seizures, previously known as partial seizures, occur in one specific part of the brain. They can be simple (without loss of consciousness) or complex (with impaired awareness or consciousness).
Who is affected?
Focal seizures can affect anyone, though they are more common in individuals with brain injuries, infections, or structural brain abnormalities.
Diagnosis:
EEG is the primary diagnostic tool for identifying focal seizures. Brain imaging techniques like MRI or CT scans are used to identify any structural issues in the brain that might be causing the seizures.
Symptoms:
- Uncontrolled movements in one part of the body, such as twitching in a hand or face
- Confusion or disorientation
- Unusual sensations, like a feeling of déjà vu or strange smells
- Loss of awareness or responsiveness during the episode
Treatment:
Treatment typically involves antiepileptic drugs, such as carbamazepine, oxcarbazepine, or levetiracetam. Surgery or other interventions may be necessary if seizures are resistant to medication.
Doctor Selection:
A neurologist specializing in epilepsy is the best option for diagnosing and managing focal seizures. For refractory cases, an epileptologist can help explore surgical or advanced treatment options.
Precautions:
- Monitoring for seizure frequency and any side effects from medications.
- Avoiding activities that may be dangerous during a seizure, such as swimming or operating machinery.
Role of Family:
Family members should be prepared to assist during a seizure and monitor the patient’s health and behavior for any changes that may indicate worsening conditions.
Status Epilepticus
What is it?
Status epilepticus is a medical emergency characterized by continuous or rapidly repeating seizures without regaining consciousness between episodes. It can occur with any type of seizure, including generalized and focal seizures.
Who is affected?
Status epilepticus can affect people of all ages, though it is more common in individuals with poorly controlled epilepsy or those who have stopped taking their anticonvulsant medication.
Diagnosis:
Status epilepticus is diagnosed based on clinical presentation. Immediate medical attention is necessary to distinguish it from other conditions that may mimic seizure activity. EEG and blood tests are essential to determine the underlying cause and monitor brain activity.
Symptoms:
- Continuous seizures lasting more than 5 minutes
- Impaired breathing or heart function during seizures
- Loss of consciousness for prolonged periods
- Physical injury or exhaustion due to repeated seizures
Treatment:
Immediate medical intervention is critical. First-line treatments include benzodiazepines, such as lorazepam or diazepam, followed by other anticonvulsant medications if seizures persist. The underlying cause of the seizures, such as infection or drug withdrawal, should also be addressed.
Doctor Selection:
In emergency situations, a neurologist or emergency care specialist will manage status epilepticus. After stabilization, a neurologist will oversee long-term management and preventive measures.
Precautions:
- Ensure emergency medical care is available at all times for patients at high risk.
- Regular follow-ups with an epilepsy specialist to monitor treatment efficacy.
Role of Family:
Family members should call emergency services immediately if a seizure lasts longer than 5 minutes. They should stay calm, protect the patient from injury, and assist with medical history documentation.
