This guide provides an in-depth look at managing seizures and epilepsy, covering types, diagnosis, treatments, and lifestyle tips. Many individuals can control or eliminate seizures through proper care, improving quality of life and enabling active living.
Seizures are brief episodes caused by abnormal electrical activity in the brain, often referred to as epileptic events. During a seizure, excessive nerve signals lead to various physical symptoms. When a person has multiple unprovoked seizures, a diagnosis of epilepsy is made. These episodes are not triggered by obvious causes like infections or low blood sugar. Diagnosing epilepsy involves excluding other conditions such as fainting or poisoning.
About 1% of the world's population is affected by epilepsy, with 5-10% experiencing at least one seizure by age 80. Effective treatments are available for approximately 70% of patients, including medication, lifestyle adjustments, surgery, or neurostimulation for resistant cases. Proper management can reduce seizure frequency and intensity over time.
Seizure Types
Seizures mainly fall into convulsive and non-convulsive types. Non-convulsive seizures are less common and harder to detect due to their brief duration. The main difference lies in the brain areas involved: generalized seizures impact both hemispheres, while partial seizures originate from specific regions.
Generalized Seizures
These include Tonic-Clonic, Tonic, Clonic, Absence, Myoclonic, and Atonic seizures. Absence seizures typically last 10-30 seconds, causing brief attention and consciousness lapses, often in children. Tonic-Clonic seizures last over 30 seconds and involve body stiffening, rhythmic jerks, and post-seizure confusion. Atonic seizures cause sudden muscle weakness leading to falls; myoclonic seizures involve rapid muscle jerks.
Partial (Focal) Seizures
Partial seizures can be simple or complex. They often begin with an ‘aura,’ such as visual or sensory changes. Simple partial seizures do not affect consciousness, whereas complex partial seizures alter awareness without fainting. Symptoms depend on the affected brain area, and some type may progress into generalized seizures.
Seizure and Epilepsy Treatment
Many seizures can be effectively controlled or eliminated with proper treatment. Diagnosis involves imaging procedures like MRI and EEG to determine seizure type. The main treatment is anticonvulsant drugs (AEDs), which prevent recurrence but do not cure the condition. Common medications include Sodium Valproate, Carbamazepine, and Levetiracetam.
For drug-resistant epilepsy, surgery might be an option, especially for focal seizures with a specific origin. Surgery aims to remove the seizure focus to prevent episodes. Consistent medication use, adequate sleep, nutritious meals, and exercise are essential lifestyle measures to decrease seizure risk. Advances in treatments allow many people with epilepsy to enjoy active, fulfilling lives.
