If you’ve ever experienced a sudden jolt or electric-like shock in your head, you might be wondering why these strange head sensations happen and what triggers them. Often described as “electrical shocks” or “brain shivers,” they’re a real phenomenon—especially for those stopping antidepressants or dealing with anxiety.
Clinical studies indicate that 40–60% of individuals who discontinue antidepressants develop withdrawal symptoms, with brain zaps being among the most frequently reported. While typically not associated with long-term harm, these episodes can be distressing and disruptive. This article reviews the potential triggers, underlying mechanisms, and management strategies for brain zaps.

Brain zaps are brief, shock-like sensations in the brain. People often describe them as feeling like a sudden jolt, static electricity, or a wave of dizziness that travels through the head. Sometimes, people say they can “hear their eyes move” or feel disoriented for a few seconds.
Brain zap feels vary from person to person—some describe them as a quick brain shock, others as a buzzing snap or internal electrical pulse.
These sensations are often accompanied by sensory disturbances, such as:
While these symptoms may seem alarming, brain zaps do not indicate permanent brain damage. However, they are often a symptom of antidepressant withdrawal and can signal an abrupt change in brain chemistry.
There’s still a lot to learn, but researchers believe the main causes of brain zaps are related to changes in serotonin levels in the brain.
The most common triggers for this symptom include:
One of the top causes is antidepressant discontinuation syndrome. This can happen when someone stops taking certain medications—especially selective serotonin reuptake inhibitors (SSRIs)—suddenly or too quickly.
SSRIs work by balancing serotonin levels in the brain. When these medications are suddenly removed, the drop in serotonin can cause shock-like sensations or electrical imbalances, leading to brain zaps.
Even if you’re still on antidepressants, missing a dose or changing your dosage can lead to symptoms. People commonly report experiencing brain zaps when switching from one SSRI to another or reducing their dosage.
Anxiety and brain activity are closely linked. For some, brain zaps and anxiety go hand in hand. Chronic stress and panic attacks can cause irregular brain signaling, which may explain the sudden jolts people feel during intense anxiety episodes.
Some people experience brain zaps when moving their eyes rapidly. This is thought to be a type of sensory disturbance linked to electrical signals misfiring in the brain. The feeling that you can “hear your eyes move” often falls under this category.
Most people who report brain zaps have one thing in common: they are experiencing withdrawal symptoms, including brain zaps, which are a key symptom of antidepressant discontinuation.
Many people search for answers about brain zaps withdrawal after stopping antidepressants, especially SSRIs, because these symptoms can feel alarming and unexpected.
This is especially true for people coming off SSRIs like:
These medications affect how the brain processes serotonin. When the drug is reduced or removed, it may take time for the brain to adjust, leading to symptoms such as:
To reduce your chances of experiencing withdrawal, doctors often recommend gradually tapering off your medication under supervision.
Brain zaps are more common in:
Even though brain zap symptoms are often temporary, they can be overwhelming. That’s why it’s important to recognize them early and speak with a mental health professional if needed.
There’s no single answer. For some, brain zaps last just a few days. For others, they may occur on and off for weeks. Factors that influence the duration include:
Remember, brain zaps aren’t dangerous, but they’re a clear sign your brain is adjusting to chemical changes.
There’s no specific medication to stop brain zaps, but there are ways to manage them. Here are a few treatment options that may help:
These sudden jolts can feel scary, but they’re usually harmless and temporary. They often signal that your brain is adjusting to medication withdrawal or reacting to anxiety and stress. While the science behind them isn’t fully understood, knowing the causes of brain zaps can reduce fear and confusion.
If you’re dealing with brain zaps, don’t go through it alone. A mental health professional can help guide your recovery and ensure you feel safe and supported as your brain stabilizes.
