Seizures in TEA patients commonly occur upon waking suggesting a link between TEA and sleep. It is possible that abnormal electrical activity during sleep disrupts the process of memory consolidation which normally occurs when we sleep. On-going subclinical seizure activity has implications for theories of memory consolidation, discussed below.
Epilepsy is a group of non-communicable neurological disorders characterized by recurrent epileptic seizures. [10] An epileptic seizure is the clinical manifestation of an abnormal, excessive, and synchronized electrical discharge in the neurons. [1]
A seizure is a paroxysmal episode of symptoms or altered behavior arising from abnormal excessive or synchronous brain neuronal activity. [5] A focal onset seizure arises from a biological neural network within one cerebral hemisphere, while a generalized onset seizure arises from within the cerebral hemispheres rapidly involving both hemispheres.
[3] [8] If a seizure lasts longer than 5 minutes, it is a medical emergency (status epilepticus) and needs immediate treatment. [3] [5] [9] Seizures can be classified as provoked or unprovoked. [3] [6] Provoked seizures have a cause that can be fixed, such as low blood sugar, alcohol withdrawal, high fever, recent stroke, and recent head trauma.
When an abnormality of the brain is suspected, stereotactic (probing in three dimensions) brain needle biopsy is performed and guided precisely by a computer system to avoid serious complications. A small hole is drilled into the skull, and a needle is inserted into the brain tissue guided by computer-assisted imaging techniques (CT or MRI scans).
It received praise for brevity, being only 39 pages, and lacking the illustrations which had graced its predecessors. Like the NHS Plan 2000 with which Stevens was also associated it was supported by the great and good of the NHS, but in this case it was regulators - Monitor, the Care Quality Commission and the like, rather than the Royal Colleges and Trades Unions of the earlier plan.
A digital application has been developed for use in clinical settings that measures three of the vital signs (not temperature) using just a smartphone, and has been approved by NHS England. The application is registered as Lifelight First , and Lifelight Home is under development (2020) for monitoring-use by people at home using just the camera ...
The number of people with PNES ranges from 2 to 33 per 100,000. [6] PNES are most common in young adults, particularly women. [6] The prevalence for PNES is estimated to make up 5–20% of outpatient epilepsy clinics; 75–80% of these diagnoses are given to female patients and 83% are to individuals between 15 and 35 years old.
