If a 75-year-old man has nothing but transient epilepsy, it is usually not sudden death, but it depends on factors such as the duration of the seizure and the environment, and in some cases it may lead to death. The clinical manifestations of epilepsy are characterized by seizures, transient, repetitive and stereotyped. Seizures are usually short in duration, and they recover spontaneously without special treatment, and are generally not life-threatening. Therefore, a 75-year-old man with no underlying disease and only brief seizures will not die suddenly. However, if the patient is in a dangerous environment, such as drowning, car accident, etc., or if the epilepsy lasts for a long time, it may lead to a lack of oxygen in the brain, and in severe cases, the brain cells will be severely damaged due to the lack of oxygen, in which case sudden death is possible. If transient epilepsy occurs in 75-year-olds without underlying diseases, it is recommended that they seek timely medical attention, and try to do less dangerous sports in general to avoid the seizures that can bring harm to themselves.
