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 ...
Transient amnesia can be the principal manifestation of epilepsy. This diagnosis, however, is "seldom suspected by clinicians and remains controversial". [4] TEA is "almost always misdiagnosed" according to a leading authority. [9] In the largest study to date (2007) "Epilepsy was the initial specialist diagnosis in only 12 of 50 cases."
When used on its own, the term seizure usually refers to an epileptic seizure. The lay use of this word can also include sudden attacks of illness, loss of control, spasm or stroke. [ 4 ] Where the physician is uncertain as to the diagnosis, the medical term paroxysmal event and the lay terms spells , funny turns or attacks may be used.
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
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).
LGS is seen in approximately 4% of children with epilepsy, and is more common in males than in females. [13] Usual onset is between the ages of three and five. [7] Children can have no neurological problems prior diagnosis, or have other forms of epilepsy. West syndrome is diagnosed in 20% of patients before it evolves into LGS at about 2 years ...
Dementia is a devastating disease that impacts one in 10 older Americans. But while many people want to avoid developing dementia, the exact causes of the condition have remained largely a mystery ...
The diagnosis may be made on the clinical features alone, along with tests to rule out other possible causes. An EEG will usually show the electrical features of epilepsy and slowing of brain activity in the affected hemisphere, and MRI brain scans will show gradual shrinkage of the affected hemisphere with signs of inflammation or scarring. [9]
