Introduction: The Double-Edged Sword of Seizure Control In the intersection of neurology and criminal law, few medications are as controversial as Levetiracetam, commonly marketed as Keppra. While it is a “gold standard” treatment for preventing epileptic seizures, its neuropsychiatric side effects are well-documented in medical literature yet frequently misunderstood in the courtroom.
For defendants with epilepsy, the distinction between criminal intent (mens rea) and medication-induced psychosis is often lost. This article explores the forensic reality of “Keppra Rage” and why the legal system must evolve to understand forensic pharmacology.
1. The Science of “Keppra Rage” Levetiracetam is unique because it doesn’t just suppress seizures; it modulates neurotransmitter release. For a subset of patients—estimated between 13% and 16% in clinical studies—this modulation results in severe behavioral changes.
- Aggression & Hostility: Patients with no history of violence can experience sudden, uncharacteristic outbursts.
- Post-Ictal Psychosis: Following a seizure event, the brain is in a fragile state. When combined with high doses of Levetiracetam, the patient may enter a dissociative state where they are conscious but not in control of their actions or speech.
2. The “False Confession” Phenomenon One of the most dangerous side effects for a legal defendant is disinhibition. Under the influence of adverse medication reactions, individuals may exhibit:
- Confabulation: Creating false memories to fill gaps in consciousness.
- Compliance: Agreeing with authoritative figures (like investigators) to end a stressful interrogation, even if the admission is factually untrue.
- Emotional Blunting: Appearing to lack remorse or empathy, which juries often misinterpret as “cold-bloodedness” rather than a chemical symptom.
3. Legal Culpability vs. Medical Toxicity The legal standard for guilt requires intent. However, a brain under the influence of severe adverse drug reactions is arguably operating under Involuntary Intoxication.
- The Gap: Most courts treat prescription drug reactions as “voluntary” because the patient took the pill.
- The Reality: If a patient takes a prescribed dose to save their life (prevent seizures) and suffers a psychotic break as a side effect, they have not “chosen” to be intoxicated. They are victims of a medical adverse event.
Conclusion: The Need for Forensic Pharmacology When the prosecution points to “erratic behavior” or “strange statements” as evidence of guilt, the defense must point to the Science. Justice requires us to ask: Was this the person speaking, or was this the side effect? For more on the intersection of disability rights and due process, follow the Willow Cherry Justice Initiative.

Clinical Validity of Levetiracetam-Induced Aggression
Source: Journal of Neurology (2025)
Summary: “Keppra Rage” is a documented adverse event characterized by hostility, aggression, and behavioral changes in 13-16% of patients. This provides the medical basis for an Involuntary Intoxication defense.
Relevant Case Precedent
People v. Garris (NY): Established that “not guilty by reason of mental disease or defect” is a viable defense when aggression is triggered by anti-seizure medication toxicity.
