EEG plays a critical role in post-stroke care by helping detect both convulsive and nonconvulsive seizures, assess the risk of post-stroke epilepsy, and guide anti-seizure medication management.

Commonly Observed EEG Patterns in Post-Stroke Patients:
🧠 Periodic Discharges (PDs/LPDs) - strong indicators of elevated risk for seizure recurrence.
🧠 Focal Slow Wave Activity (FSWA) - linked to worse functional outcomes and higher risk of seizure.
🧠 Ictal Epileptiform Abnormalities - direct evidence of seizure activity, often necessitating immediate treatment.

⚙️ EEG: Pitfalls in Reactivity Testing
EEG reactivity is a cornerstone of coma prognostication, but misinterpretation is common, especially in sedated or critically ill patients. Distinguishing true non-reactivity from technical or pharmacologic suppression is essential for accurate reporting.

🧠 Why it matters: False “non-reactive” readings can lead to inaccurate prognoses. Sedatives, metabolic factors, or poor testing technique can mask cortical responsiveness without implying irreversible injury.

💡 Tech Tip – Avoid These Common Pitfalls:
1. Sedation Confounders – Agents like propofol, midazolam, or barbiturates can profoundly blunt reactivity. Always note the timing, dose, and weaning status when testing.
2. Artifact Misinterpretation – Movement, ventilator, or ECG artifacts can mimic “reactivity.” Confirm cortical origin across derivations.
3. Weak or Inconsistent Stimuli – Use firm, reproducible auditory, tactile, and noxious stimulation.
4. Single-Modality Testing – A patient may react to touch but not sound. Use multimodal testing for accuracy.
5. State Variability – Repeat testing during lighter background states; reactivity may emerge later.
6. Technical Oversights – Check filters, impedance, and montage setup before labeling “non-reactive.”

⚙️ EEG: The Subtleties of Reactivity
EEG reactivity reflects the brain’s ability to respond to external stimuli — a key marker of cortical integrity and prognosis, especially in comatose or post–cardiac arrest patients.

🧠 Why it matters: Reactivity isn’t simply “present” or “absent” – it’s about pattern-specific modulation. A reactive shows consistent, repeatable changes in frequency or amplitude after auditory, tactile, or noxious stimulation.
• Preserved reactivity implies intact thalamocortical pathways and better neurologic outcomes.
• Absent reactivity, confirmed across modalities, may reflect severe cortical/subcortical dysfunction – but always consider sedation confounders.
• Reactivity can appear as desynchronization, amplitude attenuation, or beta activation, depending on state.

💡 Tech Tip:
✅ Test multiple stimulus types: auditory (clap, name call), tactile (touch, nail bed pressure), and noxious (sternal rub, suction).
✅ Repeat each stimulus to confirm reproducibility.
✅ Describe the EEG change.
✅ Note state context – reactivity may appear only during certain background patterns or transitions.
✅ Avoid false negatives by verifying EEG settings and artifacts.

Clear, structured reactivity documentation helps physicians interpret cortical responsiveness and guide prognostic discussions with confidence.

🎛️ Think of EEG montages like playlists – the right one changes the whole vibe.

🧠 Why it matters: Some rhythms only show up when viewed through the right montage (hello, temporal spikes).

💡 Tech Tip: When in doubt, switch it up – bipolar for localization, referential for confirmation. The more you remix, the clearer the signal.

🧠 Case Summary:
A 64-year-old left-handed man experienced frequent focal sensorimotor seizures for about a year, described as electric shock–like sensations in the right thumb and forefinger, often triggered by hand movements.

🎥 Video-EEG Findings:
Seizures were reproducibly evoked by right-hand tapping, with ictal discharges localized to the left central and parietal regions — correlating with the sensorimotor symptoms.

🩻 Imaging:
MRI and CT revealed a metal splinter embedded in the left postcentral gyrus, near the hand k**b region, from a scalp injury sustained in infancy during a wartime air raid.

💊 Treatment & Outcome:
After multiple failed antiseizure medications, seizure control was finally achieved with levetiracetam and perampanel, maintaining near-complete remission for four years.

🔑 Key Point:
This case illustrates reflex epilepsy triggered by somatosensory input—in this instance, hand movement stimulating an epileptogenic zone within the contralateral perirolandic cortex.

⚙️ Remember electrodes have feelings, too! 🎧 Poor contact = poor data.

🧠 Why it matters: Loose electrodes can mimic focal slowing or create phantom spikes.

💡 Tech Tip: If one channel looks suspicious, check the electrode, not the patient. Even the best amplifier can’t fix a flaky connection.
