Seizures
A seizure is a sudden, uncontrolled burst of electrical activity in the brain. It can cause changes in behavior, movements, feelings and levels of consciousness. Understanding the different types of seizures is crucial for accurate diagnosis, treatment, and management. The mnemonic ICTUS can help remember the key signs of a seizure:
Recognizing these signs is crucial for promptly recognizing a seizure and providing appropriate first-aid response to ensure the person's safety until the seizure subsides. Generalized Seizures: Absence Seizures or Petit Mal. These seizures are characterized by a brief loss of awareness, during which the individual stares off into space. They may experience a temporary lapse in consciousness, followed by a rapid regaining of awareness. Absence seizures are often associated with childhood absence epilepsy and can occur multiple times a day. Tonic-clonic Seizures or Grand Mal. These are the most dramatic and commonly recognized seizures. They involve a sudden loss of consciousness, accompanied by muscle stiffening (tonic phase), followed by jerking movements of the limbs and body (clonic phase). Other features may include tongue biting, incontinence, and a post-ictal state with confusion and fatigue after the seizure. Tonic Seizures. In this type of seizure, the muscles become stiff and rigid, causing the body to become tense and immobile. Tonic seizures can lead to falls and injuries if not properly managed. Atonic Seizures. Also known as "drop attacks," atonic seizures involve a sudden loss of muscle tone, causing the individual to collapse or fall abruptly. Clonic Seizures. These seizures are characterized by repetitive, jerking movements of the muscles, often affecting one or more limbs or the entire body. Myoclonic Seizures. Myoclonic seizures involve brief, shock-like jerks or twitches of a muscle or a group of muscles. Focal or Partial Seizures: Simple Focal Seizures These seizures do not cause a loss of consciousness, but they can produce symptoms such as changes in sensation, jerking or twitching movements, tingling, strange smells, or flashing lights. The individual remains aware during these seizures. Complex Focal Seizures In this type of seizure, the individual experiences impaired consciousness or altered awareness. Symptoms may include staring off, confusion, repetitive motions, and unresponsiveness. Secondary Generalized Seizures These seizures begin as a focal seizure in one part of the brain but then spread to involve both hemispheres, resulting in a generalized tonic-clonic seizure. Status epilepticus Status epilepticus is a serious seizure lasting over 5 minutes or repeated seizures without recovery. It's a medical emergency requiring immediate care to avoid brain damage or death. Take Home Message It is important to note that seizures can vary in their presentation, severity, and duration. Accurate diagnosis by a healthcare professional is essential for determining the appropriate treatment approach, which may include medications, lifestyle modifications, or surgical interventions in some cases.
