It is an abnormal interictal pattern, consisting of high amplitude and irregular waves and spikes in a background of chaotic and disorganized activity seen on electroencephalogram (EEG), and frequently encountered in infants diagnosed with infantile spasms, although it can be found in other conditions such as tuberous sclerosis.
Fetal electroencephalography, also known as prenatal EEG includes any recording of electrical fluctuations arising from the brain of a fetus. Doctors and scientists use EEGs to detect and characterize brain activity, such as sleep states, potential seizures, or levels of a coma .
EEG can detect abnormal electrical discharges such as sharp waves, spikes, or spike-and-wave complexes, as observable in people with epilepsy; thus, it is often used to inform medical diagnosis. EEG can detect the onset and spatio-temporal (location and time) evolution of seizures and the presence of status epilepticus .
By its diagnostic definition (under the name "brief psychotic disorder with peripartum onset"), PPP occurs either during pregnancy or within 4 weeks of delivering the infant. [3] Generally, PPP symptoms have been observed within 3–10 days of childbirth, though women with a past history of bipolar disorder may experience symptoms even sooner.
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.
A seizure is a sudden change in behavior, movement or consciousness due to abnormal electrical activity in the brain. [3] [6] Seizures can look different in different people.. It can be uncontrolled shaking of the whole body (tonic-clonic seizures) or a person spacing out for a few seconds (absence seizure
Neurodevelopmental disorders are a group of mental conditions affecting the development of the nervous system, which includes the brain and spinal cord.According to the American Psychiatric Association Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, published in 2013, these conditions generally appear in early childhood, usually before children start school, and can ...
Infantile epileptic spasms syndrome (IESS) previously known as West syndrome needs the inclusion of epileptic spasms for diagnosis. [1] Epileptic spasms (also known as infantile spasms) may also occur outside of a syndrome (that is, in the absence of hypsarrhythmia and cognitive regression) - notably in association with severe brain disorders (e.g. lissencephaly).
