A brain injury can cause seizure(s) because of the unusual amount of energy that is discharged across of the brain when the injury occurs and thereafter. A disruption of the supply of oxygen may cause damage to the temporal lobe of the brain. [35] The risk of seizure(s) from a closed head injury is about 15%. [36]
Brief seizures, such as absence seizures lasting 5-10 seconds, do not cause observable brain damage. [43] More prolonged seizures have a higher risk of neuronal death. [ 43 ] Prolonged and recurrent seizures, such as status epilepticus, typically cause brain damage. [ 43 ]
In the elderly, hypoglycemia can produce focal stroke-like effects or a hard-to-define malaise. [medical citation needed] The symptoms of a single person do tend to be similar from episode to episode. In the large majority of cases, hypoglycemia severe enough to cause seizures or unconsciousness can be reversed without obvious harm to the brain.
Confusion, difficulty speaking, seizures. Cerebral hypoxia is a form of hypoxia (reduced supply of oxygen), specifically involving the brain; when the brain is completely deprived of oxygen, it is called cerebral anoxia. There are four categories of cerebral hypoxia; they are, in order of increasing severity: diffuse cerebral hypoxia (DCH ...
Status epilepticus (SE), or status seizure, is a medical condition consisting of a single seizure lasting more than 5 minutes, or 2 or more seizures within a 5-minute period without the person returning to normal between them. [3][1] Previous definitions used a 30-minute time limit. [2] The seizures can be of the tonic–clonic type, with a ...
Anything that causes epilepsy causes epileptogenesis, because epileptogenesis is the process of developing epilepsy. Structural causes of epilepsy include neurodegenerative diseases, traumatic brain injury, stroke, brain tumor, infections of the central nervous system, and status epilepticus (a prolonged seizure or a series of seizures ...
Central nervous system diseases or central nervous system disorders are a group of neurological disorders that affect the structure or function of the brain or spinal cord, which collectively form the central nervous system (CNS). [1][2][3] These disorders may be caused by such things as infection, injury, blood clots, age related degeneration ...
Temporal lobe in green. In the field of neurology, temporal lobe epilepsy is an enduring brain disorder that causes unprovoked seizures from the temporal lobe. Temporal lobe epilepsy is the most common type of focal onset epilepsy among adults. [1] Seizure symptoms and behavior distinguish seizures arising from the medial temporal lobe from ...
