Oct 14, 2023 · Epilepsy happens as a result of abnormal electrical brain activity, also known as a seizure, kind of like an electrical storm inside your head. And because your brain controls so much, a lot of different things can go wrong.
A seizure is a sudden burst of electrical activity in the brain. It can cause changes in behavior, movements, feelings and levels of consciousness. Epilepsy is defined as having two or more seizures at least 24 hours apart that don't have a known cause. But epilepsy doesn't cause all seizures.
Oct 13, 2023 · Others may cause life-threatening symptoms. There are times when it is OK to have a fast or slow heartbeat. For example, the heart may beat faster with exercise or slow down during sleep. Heart arrhythmia treatment may include medicines, devices such as pacemakers, or a procedure or surgery.
May 29, 2024 · EEG brain activity. An EEG records the electrical activity of the brain via electrodes attached to the scalp. EEG results show changes in brain activity that may be useful in diagnosing brain conditions, especially epilepsy and other conditions that cause seizures.
Apr 7, 2023 · Temporal lobe seizures begin in the temporal lobes of the brain. These areas process emotions and are important for short-term memory. Symptoms of a temporal lobe seizure may be related to these functions. Some people have odd feelings during the seizure, such as joy, deja vu or fear.
Jul 19, 2024 · It happens when excess sweating is not triggered by a rise in temperature or physical activity. Primary hyperhidrosis may be at least partly hereditary. If the excess sweating is due to an underlying medical condition, it's called secondary hyperhidrosis.
May 30, 2024 · Parkinson's disease. Parkinson's disease causes tremors, muscle stiffness, slow or decreased movement, or loss of balance. It also can cause symptoms not related to movement. These symptoms include a reduced sense of smell, constipation, acting out dreams and a decline in thinking skills.
Aug 6, 2024 · The condition can make it harder for the heart to pump blood. The most common cause is high blood pressure. Left ventricular hypertrophy is thickening of the walls of the lower left heart chamber. The lower left heart chamber is called the left ventricle. The left ventricle is the heart's main pumping chamber.
May 5, 2021 · Myocardial ischemia, also called cardiac ischemia, reduces the heart muscle's ability to pump blood. A sudden, severe blockage of one of the heart's artery can lead to a heart attack. Myocardial ischemia might also cause serious abnormal heart rhythms. Treatment for myocardial ischemia involves improving blood flow to the heart muscle.
Frontal lobe seizures tend to occur in clusters. For this reason, they might provoke a condition in which seizure activity lasts much longer than usual, known as status epilepticus. If these seizures continue, they can cause permanent brain damage or death. Seizures that last longer than five minutes are medical emergencies.
