– ADD/ADHD– Depression– Migraines
• General Recommendations

Factors Influencing EEG

Concentration/Relaxation Cycle
copyright 2012 T. F. Collura
Phenotypes
• Diffuse Slow• Focal Abnormalities, not epileptiform• Mixed Fast & Slow• Frontal Lobe Disturbances – excess slow• Frontal Asymmetries• Excess Temporal Lobe Alpha• Spindling Excessive Beta• Generally Low Magnitudes• Persistent Alpha• “Epileptiform” (requires visual inspection of EEG waveforms)• Faster Alpha Variants, not Low Voltage (requires live z-score
for peak frequency)• + Diffuse Alpha deficit
copyright 2012 T. F. Collura
Common EEG Deviations
• Depression– Asymmetric frontal alpha– Also beta excess or deficit variants
• OCD– Excess orbitofrontal, temporofrontal alpha
• ADHD– Frontal slowing, frontal theta, excess central alpha– Also low-voltage variants

Drugs and EEG
copyright 2012 T. F. Collura
EEG changes due to medications
• Opioids / Cannabis / PCP / Antidepressants– Increase slow wave activity
• Barbiturates– Rhythmic 18 to 26 Hz activity
• Neuroleptics / Tranquilizers– Increase coherence, decrease beta
• Anxiolytics– Decrease alpha, increase beta
• SSRI’s– Increase fronto-central beta
copyright 2012 T. F. Collura
Atypical Antipsychotics
• Dopamine and Serotonin agonist• Side effects: constipation, extrapyramidal, sedation,
tremor, restlessness• Anecdotal reports of seizures, convulsions• Arora and Arndorfer (2007) reported twitching, spells
with Aripiprazole (Abilify)• EEG revealed “generalized epilepsy,” “seizure activity”

General Principles• Record, classify EEG and/or QEEG• Identify particular markers or traits• Associate with likely mechanisms• Consider effects of drugs on EEG• Assess likelihood of positive outcome for
– Medication– Neurofeedback– Other Therapies
copyright 2012 T. F. Collura
ADD/ADHD
• At least 5 subtypes identified• Distinct EEG signatures• Prognostic for EEG Biofeedback• Prognostic for Stimulant Effectiveness• May point to alternative medications
copyright 2012 T. F. Collura
Depression
• Two basic forms:– Left/Right Frontal Asymmetry
• Davidson, Rosenfeld, Baehr
– Localized or General Beta Excess/Deficit• Hirshberg / Brown / Tufts / Harvard
copyright 2012 T. F. Collura
Anxiety
• Various EEG manifestations– Excess beta– Excess alpha– Alpha deficit
copyright 2012 T. F. Collura
General EEG-Based Pharmacotherapy
• Phenotype-Based– Arns et al. ADD/ADHD subtyping
• QEEG-Based– DeBattista, Hoffman, CNS Response

Migraines
• Walker (2011) compared EEG with• Medication Effectiveness• EEG Biofeedback Effectiveness

Arns et al. (2012)
• ADHD patients with excess frontal theta EEG power and excess frontal alpha EEG power are more likely to respond to stimulant medication
• Low-voltage EEG occurs more often in ADHD than in controls
• These three subgroups reflect “lower and more instable vigilance regulation”
• Contrast to “vigilance auto-stabilization (Hegerl, Sander) which are less responsive to stimulants
copyright 2012 T. F. Collura
Arns et al. (2012)
• Another subgroup: excess beta or beta spindling (Arns, Chabot, Serfonetin, Clarke)
• Lack of improvement on impulsivity and inattention in response to stimulants.
• Slowed individual Alpha Peak Frequency (iAPF) also do not respond to stimulant medication.
• Non-specific trait; also non-responsive to antidepressants and rTMS

Summary
• ADD/ADHD– Subtyping, differential response to stimulants– Slow-wave variants respond to stimulants
• Depression– Frontal Asymmetry type responds to antidepressants– Avoid SSRI’s when excess or spindling beta present
• Migraines– Medication of limited long-term value– EEG can be used to select NF
