What EEG finding is most often associated with metabolic, especially hepatic, encephaolpathy?
|
triphasic waves
|
|
|
What EEG finding is ost often associated with subacute sclerosing panencephalitis (SSPE)?
|
Periodic bursts every 4 to 15 seconds
|
|
|
What EEG finding is most often associated with herpes simplex encephalitis (HSE)?
|
focal temporal spikes or sharp waves that can be unilateral or bilateral usually occurring periodically at a rate of 1 to 3 seconds
|
|
|
What EEG finding is modt often associated with severe anoxic encephalopathy?
|
Burst suppression that may or may not be associated with clinical myoclonic jerks
|
|
|
What EEG finding is most often associated with Creutzfeldt-Jakob disease?
|
Initially the EEG shows slower than normal activity with loss of normal background. WEith disease progression bursts of moderate voltage biphasic and triphasic sharp waves at intervals of about 1 per second.
|
|
|
What EEG finding is most often associated with meningitis?
|
Generalized with slowing of the background, progression to polymorphic high voltage delta activity frontally predominant or low voltage slow burst suppression activity.
|
|
|
What EEG finding is most often associated with a cerebral abscess?
|
highly localized polymorphic delta waves over area with abscess
|
|
|
What type of EEG activity most often appears in association with rapidly growing tumors such as glioblastoma mulitforme and cerebral metastatic lesions
|
polymorphic delta
|
|
|
What EEG findings are most often associated with Alzheimer's disease?
|
Initially may be normal, progresses to diminished voltage and amount of alpha activity, increased theta and delta activity intrudes with some sharp activity being present. Sleep spindles are less clearly seen and K-complexes may be sparse.
|
|
|
What EEG finding is most often associated with normal pressure hydrocephalous?
|
may be normal or may show minimal nonspecific slow wave activity.
|
|
|
What EEG finding is most often associated with Huntington's Chorea?
|
earlyin the disease usually normal, progresses to a low voltage pattern ( less than 10 uV) and no organized rhythms.
|
|
|
What EEG finding is most often associated with Parkinsons's disease?
|
no specific EEG findings with Parkinson's disease
|
|
|
Describe the EEG seen in a patient with chronic alcohol use.
|
low voltage fast activity, lower amplitude and decreased frequency alpha
|
|
|
What EEG effect is seen with diazepam?
|
diffuse high amplitude beta
|
|
|
What EEG changes are seen with phenobarbital?
|
frontal beta activity
