Innovation in Psychiatry Practice with Cognision EEG
Medicare and major insurance carriers reimburse for EEG. Because it is so easy to use it's perfect as part of a protocol for in-office evaluation of Altered Mental Status which can include concussion, mild Traumatic Brain Injury (mTBI), post-concussion syndrome, Alzheimer's and psychiatric disorders. No technician is required.
EEG Assessment in ADHD
EEG is a useful test in adult psychiatry.
STUDY MAIN POINTS - Patients with new-onset psychosis should undergo clinical examination for pathological changes in the brain using a standard EEG test. Psychiatric patients with sudden or stereotypical seizure episodes accompanied by changes in consciousness, behaviour or mood should also be assessed for epilepsy using EEG.
STUDY CONCLUSION - EEG is indicated in patients with new-onset psychosis, conditions characterised by rapid changes in mood or behaviour, or conditions characterised by fluctuating or progressive cognitive impairment. The purpose of using EEG is to examine whether the patient may have epileptic or slow EEG activity. Epileptiform activity is a specific sign of epileptic etiology or co-morbidity. Slow EEG activity may be a non-specific sign of brain disease, which should generally prompt further neurological examination. Where there are brief and stereotypical changes of behaviour in patients with psychiatric disorders, epilepsy should be suspected. Epileptic seizures may also manifest as, or trigger, psychiatric symptoms. Where underlying epilepsy is suspected, the general practitioner can also refer the patient for EEG.
Diagnostic EEG should be interpreted by a specialist in clinical neurophysiology. There are so many sources of error that must be identified and eliminated that any QEEG analysis should only be carried out as a supplement to a visual EEG interpretation. Pathological EEG findings will increase the indication for use of antiepileptic drugs compared with other psychotropic drugs, irrespective of the psychiatric core symptoms.
EEG and Dementia
“The early detection and classification of dementia are important clinical support tasks for medical practitioners in customizing patient treatment programs to better manage the development and progression of these diseases. Efforts are being made to diagnose these neurodegenerative disorders in the early stages. Indeed, early diagnosis helps patients to obtain the maximum treatment benefit before significant mental decline occurs. The use of electroencephalogram as a tool for the detection of changes in brain activities and clinical diagnosis is becoming increasingly popular for its capabilities in quantifying changes in brain degeneration in dementia.”
“However, several studies have appreciated the EEG as a useful clinical evaluation tool in the discrimination of AD and/or VaD and/or other types of dementia. Highly sensitive EEG-based detection of the progress of dementia and classification of its severity are a highly desirable screening technique in clinical practice as its low cost and portable features make it a promising technique that can be a reference for customizing or personalizing optimal therapeutic programs for dementia patients.”
EEG and Sleep Disturbances
“Sleep disordered breathing (SDB) is a common medical condition. Its manifestations of snoring, nocturnal choking, arousals, and sleep fragmentation can lead to excessive daytime sleepiness, neuropsychological slowing, lapses of consciousness, and accidents that can be misinterpreted as epileptic phenomena. Moreover, patients with documented epilepsy commonly exhibit similar symptomatology because of the undiagnosed coexistence of sleep apnea. Therefore, a large proportion of patients referred to the electroencephalogram (EEG) laboratory primarily to confirm or refute the diagnosis of epilepsy could suffer from latent sleep apnea and the routine EEG has the potential to divulge it.”
