Traumatic Brain Injury
To examine the incidence of severe hypocarbia (PaCO2 30 mm Hg) in patients with severe pediatric traumatic brain injury before and after publication of the 2003 pediatric guidelines (PG). Retrospective cohort analysis. Harborview Medical Center, Seattle, Washington (January 1, 1995, to December 31, 2005). Children 15[…][ncbi.nlm.nih.gov]
Meningioma
Although most meningiomas are encapsulated and benign tumors with limited numbers of genetic aberrations, their intracranial location often leads to serious and potentially lethal consequences. They are the most frequently diagnosed primary brain tumor accounting for 33.8% of all primary brain and central nervous[…][ncbi.nlm.nih.gov]
Encephalitis
Encephalitis is inflammation of the brain. Severity is variable. Symptoms may include headache, fever, confusion, a stiff neck, and vomiting. Complications may include seizures, hallucinations, trouble speaking, memory problems, and problems with hearing.Causes of encephalitis include viruses such as herpes simplex virus[…][en.wikipedia.org]
Brain Neoplasm
Continuum (Minneap Minn). 2015 Apr;21(2 Neuro-oncology):480-6. doi: 10.1212/01.CON.0000464183.35322.5f. Abstract Neurologists are often on the front lines of diagnosis for primary and metastatic brain tumors. Patients with brain tumors typically have multiple comorbidities and pain generators beyond headache,[…][ncbi.nlm.nih.gov]
Stroke
In some cases, focal slow activity may presents as focal and irregular slow activity in the delta frequency, receiving the designation of polymorphic delta activity (PDA)[scielo.br]
Thalamic lesions generally produced focal or unilateral delta activity, but the slow activity varied in time of onset, amplitude and degree of focality 16.[scielo.br]
It was first described by Walter 14, in 1936, who proposed the term "delta waves" for focal slow activity associated with tumors involving cerebral hemispheres.[scielo.br]
Temporal Lobe Epilepsy
activity and temporal lobe-onset seizures.[ncbi.nlm.nih.gov]
In this rare case of coexistent primary generalised epilepsy and focal epilepsy, the epileptic networks of the two forms of epilepsy appear to overlap.[ncbi.nlm.nih.gov]
[…] myoclonic epilepsy, to the novel appearance of interictal temporal spikes immediately preceding bisynchronous discharges, and subsequently to temporal intermittent rhythmic delta[ncbi.nlm.nih.gov]
Uncinate Seizure
focal fast activity like our case.[j-epilepsy.org]
[…] in almost 50%; in the majority of those that do show abnormalities, focal attenuation or rhythmic theta or delta is the prominent rhythm, and 10% of the abnormalities are[j-epilepsy.org]
[…] brief events in one night, usually in the space of a few hours. 10 Video-EEG recordings of NFLE show striking stereotypy between attacks. 7 Ictal EEG shows no epileptiform activity[j-epilepsy.org]
Juvenile Myoclonic Epilepsy
activity and temporal lobe-onset seizures.[ncbi.nlm.nih.gov]
In this rare case of coexistent primary generalised epilepsy and focal epilepsy, the epileptic networks of the two forms of epilepsy appear to overlap.[ncbi.nlm.nih.gov]
[…] myoclonic epilepsy, to the novel appearance of interictal temporal spikes immediately preceding bisynchronous discharges, and subsequently to temporal intermittent rhythmic delta[ncbi.nlm.nih.gov]
Stupor
EEGs in the former may show focal disturbances such as delta and theta activity, epileptiform abnormalities, and attenuation of faster frequencies.[ncbi.nlm.nih.gov]
