PNES episodes can be difficult to distinguish from epileptic seizures without the use of long-term video EEG monitoring.Some characteristics which may distinguish PNES from epileptic seizures include gradual onset, out-of-phase limb movement (in which left and right extremities jerk asynchronously or in opposite directions, as opposed to rhythmically and simultaneously as in epileptic seizures ...
Symptoms may include shaking, loss of consciousness, and loss of bladder control. [2] They may or may not be caused by either physiological or psychological conditions. [2] Physiological causes include fainting, sleep disorders, and heart arrhythmias. [2] [3] Psychological causes are known as psychogenic non-epileptic seizures. [3]
During EEG, hyperventilation can be used to provoke these seizures. [5] Ambulatory EEG monitoring over 24 hours can quantify the number of seizures per day and their most likely times of occurrence. [5] Absence seizures are brief (usually less than 20 seconds) generalized epileptic seizures of sudden onset and termination.
Absence seizures are generalized epileptic seizures that can be divided into two types, typical and atypical. Typical and atypical absence seizures display two different kinds of spike-and-wave patterns. Typical absence seizures are described by generalized spike-and-wave patterns on an EEG with a discharge of 2.5 Hz or greater.
As a functional disorder, there is, by definition, no known disease process affecting the structure of the body, yet the person experiences symptoms relating to their body function. Symptoms of functional neurological disorders are clinically recognisable, but are not categorically associated with a definable organic disease. [1] [2]
Focal motor seizures or epilepsia partialis continua are particularly common, and may be very difficult to control with drugs. [citation needed] In the chronic or residual stage, the inflammation is no longer active, but the affected individual is left with some or all of the symptoms because of the damage that the inflammation has caused. In ...
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.
The symptoms of Alzheimer's disease as a distinct nosologic entity were first identified by Emil Kraepelin, who worked in Alzheimer's laboratory, and the characteristic neuropathology was first observed by Alois Alzheimer in 1906. Because of the overwhelming importance Kraepelin attached to finding the neuropathological basis of psychiatric ...
