EEG Report Summary

Three years post-diagnosis of traumatic brain injury (TBI), the patient underwent an EEG due to persistent episodes characterized by fatigue and changes in consciousness. A diagnosis of complex migraines had been made previously. This particular EEG occurred during a period when the patient experienced temporary memory impairment, notably failing to recognize the current President, alongside fluctuating wakefulness. Subjective Report: Chief Complaint: EEG evaluation History of Present Illness: The patient is here for an EEG examination to assess episodes of changes in mental status, specifically to exclude the presence of focal or epileptiform abnormalities. Objective Report: Procedure Overview: This digital electroencephalogram, conducted during both waking and sleeping phases, follows the International 10-20 Electrodes Placement System. The recordings exhibit standard artifacts from movement, muscle tension, and chewing. Results can be analyzed using conventional montage techniques. Findings: - BACKGROUND: Normal voltage levels with a diverse frequency mix. - POSTERIOR DOMINANT RHYTHM: Recorded at 9-10 Hz. - SLOWING: Intermittent, disorganized slowing detected. - EPILEPTIFORM ABNORMALITIES: None identified. - SLEEP: Drowsiness noted, evidenced by slow, rolling eye movements and a decrease in the posterior rhythm. The patient demonstrated standard sleep architecture. - HYPERVENTILATION: Presented with normal background slowing and buildup, without any focal or epileptiform changes. - PHOTIC STIMULATION: No reaction or driving response observed; no epileptiform anomalies recorded. - EKG: Demonstrates a normal sinus rhythm in the single-channel assessment. Assessment: The EEG results indicate abnormal readings during both awake and sleep phases, showing disorganized slowing suggestive of encephalopathy. If there remains a significant concern regarding seizures, an ambulatory EEG may be warranted. It is essential to correlate these findings clinically. Diagnosis code: R40.4 for transient alteration in awareness.

The EEG results show some abnormal findings that may explain the symptoms you've been experiencing, including fatigue and changes in consciousness. While no epileptiform abnormalities were detected, there are indications of disorganized slowing, which suggests a potential encephalopathy. It’s important to correlate these EEG findings with your clinical symptoms to get a clearer picture of what might be happening.

Explanation

1. Normal Findings: There were no signs of seizures (epileptiform abnormalities) during the EEG. This is reassuring, as it indicates that the sudden changes in consciousness you’ve experienced may not be due to epilepsy.
2. Slowing: The disorganized slowing can be linked to conditions affecting brain function, potentially related to your history of traumatic brain injury and migraines.
3. Assessment: The EEG suggests the need for further clinical correlation. This might involve assessing your symptoms in detail with a healthcare provider to determine appropriate next steps.

Next Steps

1. Monitor Symptoms: Keep a detailed diary of your symptoms, including when changes in mental status occur and any associated factors, like fatigue or headaches. This information will be helpful for any future evaluations.
2. Follow-Up Consultation: Plan to discuss these EEG findings with your healthcare provider. They may recommend further evaluations or treatments based on a comprehensive review of your symptoms and the EEG results.
3. Consider Ambulatory EEG: If your symptoms persist or worsen, your healthcare provider may suggest an ambulatory EEG, which can monitor brain activity over a longer duration to capture potential episodes not recorded in this single EEG.

If you have any specific concerns or need further clarification on the findings, please feel free to ask!
