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 ...
Non-epileptic seizures (NES), also known as pseudoseizures, non-epileptic attack disorder (NEAD), functional seizures, or dissociative seizures, are paroxysmal events that appear similar to an epileptic seizure, but do not involve abnormal, rhythmic discharges of neurons in the brain. [1]
According to the 2nd edition of the International Classification of Sleep Disorders (ICSD-2), [1] confusional arousals are classified in NREM parasomnias embedded in the non-epileptic paroxysmal motor events during sleep, which include (1) Parasomnia, (2) Sleep-related movement disorders and (3) Isolated symptoms, apparently normal variants and ...
Patients present with neurodevelomental impairments and symptoms including: [1] Infantile hypotonia; Congenital ophthalmic abnormalities; Childhood onset hyperkinetic movement disorder; Stereotypical motor behaviour; Moderate to profound developmental delay or intellectual disability; Sleep disturbance; Episodic agitation
Amyloid-related imaging abnormalities (ARIA) are abnormal differences seen in magnetic resonance imaging of the brain in patients with Alzheimer's disease. ARIA is associated with anti-amyloid drugs, particularly human monoclonal antibodies such as aducanumab. [1] There are two types of ARIA: ARIA-E and ARIA-H.
Through studies, dementia is both a cause and an effect of dyschronometria. This has to do completely with the fact that with dementia the brain is constantly rewiring itself and thus information becomes lost causing the person who has dementia to become confused as well as disoriented, and in most cases completely unaware of the passage of time.
In it high amplitude waves and spikes are present, randomly appearing and with no topographical distribution identified; also, there is no frequency nor amplitude gradient, indicating a highly disorganized brain activity. Although having this seemingly chaotic EEG, the patient didn't show any clinical seizures while being recorded. Specialty ...
Ohtahara syndrome (OS), also known as Early Infantile Developmental & Epileptic Encephalopathy (EIDEE) [2] is a progressive epileptic encephalopathy.The syndrome is outwardly characterized by tonic spasms and partial seizures within the first few months of life, [3] and receives its more elaborate name from the pattern of burst activity on an electroencephalogram (EEG).
