Convulsive Disorder
Seizures, also known as convulsions or fits, are sudden changes in brain electrical activity that can manifest with a wide range of symptoms or no symptoms at all. The brain, comprising millions of neurons responsible for controlling various body functions, emotions, thoughts, memory, concentration, and personality, communicates through electrical signals. During a seizure, an abrupt and intense electrical discharge, akin to thunder and lightning, occurs, leading to alterations in a person's state of consciousness, behavior, or even loss of consciousness. Prominent symptoms of seizures may include body shaking and loss of control. Nevertheless, mild seizures can also be indicative of serious underlying medical conditions, necessitating prompt recognition and appropriate medical attention.
Seizures occur due to sudden and abnormal electrical activity in the brain, leading to a variety of reasons such as drug use, high fever, head injuries, and certain medical conditions. Individuals experiencing repeated seizures due to a brain disorder are diagnosed with epilepsy. Moreover, seizures may also arise after a stroke, accidents, infections such as meningitis, or other brain and nerve diseases.
There are two main types of seizures:
Focal seizures: Originating in a specific part of the brain, these seizures are named after the location where they occur. Focal seizures can elicit physical and emotional effects, causing sensations such as seeing or hearing things that aren't present. This type accounts for around 60% of epilepsy cases and is sometimes referred to as a partial seizure. Focal seizure symptoms may occasionally be mistaken for symptoms of mental illnesses or other neurological disorders.
Generalized seizures: These seizures involve disruptions in nerve cells on both sides of the brain and can result in muscle spasms, loss of consciousness, or falling. Some individuals may initially experience one type of seizure and subsequently transition to another. Some seizures are challenging to classify and are known as seizures of unknown onset, which may present with sensory and physical symptoms.
The symptoms of seizures can vary considerably among individuals, ranging from brief periods of staring to more severe episodes involving muscle contractions and limb trembling. Notably, experiencing seizure symptoms does not necessarily indicate epilepsy. Additionally, some individuals may experience prodromal symptoms preceding the onset of seizures, such as sudden feelings of fear or anxiety, dizziness, changes in vision, or rapid arm and leg movements that can lead to loss of balance.
Seeking medical attention from a neurologist is crucial if you or someone you know presents with any of the seizure symptoms mentioned above. A thorough evaluation is essential to accurately diagnose the underlying cause of the symptoms. Seizures can be caused by various health conditions or triggers, such as epilepsy, high fever associated with infections like meningitis, lack of sleep, medication side effects, head trauma, stroke, brain tumors, illegal drug use, alcohol abuse, electrolyte imbalances, and genetic factors. In some cases, particularly in young children, the cause of seizures may remain unknown.
Left untreated, seizures can worsen and persist for prolonged periods, potentially leading to brain dysfunction or even death. Additionally, seizures may cause injuries resulting from falls or trauma to body parts.
Diagnosing seizures involves a comprehensive assessment, including a physical examination, review of medical history and medications, and careful evaluation of seizure symptoms. Specific tests may be ordered by the physician to accurately diagnose and determine the appropriate treatment approach. It is essential to provide a complete medical history to the doctor, as conditions such as migraine headaches, sleep disorders, and severe psychological stress can also present with seizure-like symptoms. Laboratory tests may be utilized to rule out other potential causes of the condition and arrive at an accurate diagnosis. Proper management and treatment of seizures, often with medication, can significantly improve a person's quality of life and daily functioning.
