Lynda Thompson on Neurofeedback and Biofeedback Synergy
A growing body of research and clinical innovation has underscored the need to integrate multiple therapeutic modalities like neurofeedback and biofeedback when working with clients who present with complex psychological and physiological concerns.

5-Second Science: The Link Between Traumatic Brain Injury and Psychosis
Using a large nationally representative dataset, the researchers found that people hospitalized for TBI were more than twice as likely to be diagnosed with schizophrenia or other psychotic conditions than similar individuals without TBI.

Interpreting the Raw EEG: Frontal Intermittent Rhythmic Delta Activity (FIRDA)
Frontal intermittent rhythmic delta activity (FIRDA) is not a diagnosis—it’s a clue.

How Antipsychotics Affect the EEG
Ben's case exemplifies the core insight of Dr. Swatzyna’s clinician detective model: that not all psychiatric symptoms are psychiatric in origin, and that functional abnormalities in brain activity—detectable on EEG—can signal the presence of invisible, systemic pathology.

Interpreting the Raw EEG: Four Montages
All montages compare EEG activity between one or more pairs of electrode sites.

Interpreting the Raw EEG: Fast Alpha
The most pressing clinical issue surrounding fast alpha is its frequent misclassification, particularly when spectral peaks in the 18–19 Hz range are erroneously interpreted as beta spindling, pathological fast activity, or early signs of drug effects.

Interpreting the Raw EEG: Occipital Intermittent Rhythmic Delta Activity (OIRDA)
We wish clinicians knew that OIRDA is not an epileptiform discharge. It does not reflect hyperexcitability or paroxysmal depolarization, and in isolation, it is not a seizure pattern.

The Clinician Detective: Investigation Begins with Careful Observation
Before a diagnosis of a mental disorder can be made, the clinician must rule out that the symptoms are not attributable to the physiological effects of a substance or another medical condition.

How Benzodiazepines Affect the EEG
Benzodiazepines vary widely in EEG and clinical effects—Subtypes differ by half-life and receptor affinity, influencing sedation, rebound symptoms, and cortical modulation.

How Antidepressants Affect the EEG
Antidepressants, particularly those that are highly activating or serotonergically potent, may be the worst choice in patients with SEB, IEDs, or focal abnormalities.

Dr. John Davis on the Alpha Rebound Protocol for PTSD
Reduced alpha rhythms in PTSD are thought to be involved in poor excitatory/inhibitory balance in the brain.

The Clinician Detective: First Inspect the Raw EEG
Used responsibly, the qEEG enhances interpretation; used in isolation, it risks misrepresentation.

Best Practice: Small-N Research
Small-N designs are particularly powerful when the treatment effect is large and immediate, allowing researchers to infer causality with confidence.

Best Practice: Interrogating Causal Claims
To support a causal claim, a study must meet three essential criteria: covariance, temporal precedence, and internal validity.

Best Practice: Interrogating Association Claims
Interrogating association claims means asking three core questions: Were the variables measured well (construct validity)? Can the results be generalized to other populations (external validity)? And is the association statistically strong, significant, and precise (statistical validity)?

Best Practice: Interrogating Frequency Claims
The four big validities offer a comprehensive toolkit for evaluating psychological research. Construct validity ensures that variables are accurately measured or manipulated. External validity tells us whether the results generalize. Statistical validity ensures the numbers are trustworthy. Internal validity confirms that cause-and-effect relationships are legitimate.

Best Practice: Researcher Claims
Association claims are foundational to psychological research because they help us identify variables that are connected and warrant further investigation. While they cannot prove causality, they provide essential groundwork for asking deeper questions.
