A less well-known variation of the condition known as "silent migraine" or "acephalgic migraine," occurs without normal headache symptoms. We will delve into the realm of silent migraines in this blog and examine their causes, symptoms, length, connection to anxiety, and successful treatment choices.

Millions of individuals worldwide suffer from migraines, a widespread neurological condition. The majority of us are familiar with the symptoms of a migraine, which include nausea, sensitivity to light and sound, and a strong pounding headache.

What is Silent Migraine

Silent migraine, also known as acephalgic migraine or migraine aura without headache, is a unique type of migraine where individuals experience migraine aura symptoms without accompanying headache pain. Migraine aura involves temporary neurological disturbances that can occur before or during a migraine attack, affecting vision, sensory perception, motor function, or language abilities.

Despite the absence of head pain, silent migraines can be distressing due to the experienced aura symptoms. The exact cause is not fully understood, but they share underlying mechanisms with other migraine subtypes.

During a silent migraine episode, individuals may experience visual disturbances like flashing lights, zigzag lines, or blind spots, along with sensory changes such as tingling or numbness. Language difficulties, motor disturbances, mood changes, or cognitive disruptions can also manifest.

Diagnosing silent migraines can be challenging, making medical evaluation essential. While generally not dangerous, understanding and managing them is crucial. Treatment focuses on addressing aura symptoms and preventing future episodes through lifestyle changes, medication, and stress management. Recognizing and diagnosing silent migraines is vital for providing effective care and support.

What Causes Silent Migraine

Silent migraines share similar pathophysiology with other types of migraines, but they are characterized by the absence of headache pain, focusing on the manifestation of migraine aura symptoms. Key mechanisms include cortical spreading depression (CSD), neurotransmitter levels like serotonin disturbances, vascular changes, and genetic/environmental factors. CSD involves waves of neuronal hyperactivity followed by suppression, triggering aura symptoms such as visual disturbances and motor difficulties.

Changes in serotonin levels lead to blood vessel dilation and inflammation in the brain, contributing to aura symptoms. Vascular changes triggered by inflammatory substances, like serotonin and CGRP, play a role in silent migraines. Genetic predisposition and environmental triggers like stress, hormonal changes, certain foods, sensory stimuli, and weather are also influential. Understanding these mechanisms is essential for the effective management of silent migraines.

What triggers Silent Migraine

Various factors can act as triggers for silent migraines. These triggers may differ from person to person, and identifying and avoiding them can help reduce the frequency of silent migraine episodes. Some common triggers include:

Stress and Anxiety

Emotional stress and anxiety can lead to changes in neurotransmitter levels and trigger silent migraines.

Hormonal Changes

Fluctuations in hormones, particularly estrogen, can influence the development of migraines, and some individuals may experience silent migraines in relation to hormonal shifts.

Sensory Stimuli

Bright lights, strong smells, loud noises, or other sensory stimuli can initiate silent migraines in susceptible individuals.

Weather Changes

Changes in weather patterns, such as changes in barometric pressure, temperature, or humidity, have been linked to migraine attacks, including silent migraines.

Dietary Factors

Certain foods and beverages, such as aged cheese, processed meats, caffeine, alcohol, and artificial sweeteners, may trigger silent migraines in some individuals.

Sleep Disruption

Irregular sleep patterns or lack of sleep can be a trigger for silent migraines.

Physical Factors

Intense physical exertion or overexertion, such as intense exercise, can trigger migraines in some people.


Certain medications, such as hormonal contraceptives or vasodilators, may be associated with an increased risk of silent migraines.

It is essential for individuals with silent migraines to keep track of potential triggers and work with healthcare professionals to develop personalized management strategies and lifestyle adjustments to minimize the impact of these triggers and reduce the frequency of silent migraine episodes.

Symptoms of Silent Migraine

Silent migraines, also known as acephalgic migraines or migraine aura without headache, are characterized by the presence of migraine aura symptoms without the typical headache pain. The symptoms of silent migraine include:

Absence of Headache Pain

The primary distinguishing feature of silent migraines is the absence of the typical throbbing headache pain experienced in most migraine episodes. Unlike other migraine types, silent migraines focus solely on the manifestation of migraine aura symptoms without concurrent headaches.

Visual Disturbances

Visual disturbances are one of the most common symptoms of silent migraines. Individuals may experience flashing lights, zigzag lines, shimmering spots, or blind spots in their field of vision.

Sensory Changes

Some people with silent migraines may experience sensory changes such as tingling or numbness in the face, hands, or other parts of the body.

Language Difficulties

Silent migraines can also lead to language difficulties, including difficulty finding words, slurred speech, or language impairment.

Motor Disturbances

Weakness, difficulty with movement, or coordination problems can occur during a silent migraine episode.

Cognitive Disturbances

Cognitive symptoms may include confusion, difficulty concentrating, or memory problems.

Mood Changes

Mood swings, irritability, or feelings of anxiety may be present during a silent migraine episode.

It is important to note that the absence of headache pain in silent migraines can sometimes make recognizing and diagnosing the condition challenging. Keeping track of these aura symptoms and seeking medical evaluation is essential for proper diagnosis and effective management of silent migraines. Treatment may focus on managing aura symptoms and identifying and avoiding triggers to reduce the frequency and severity of silent migraine episodes.

How long does Silent Migraine last

The duration of a silent migraine can vary from person to person and from one episode to another. In general, the course of a silent migraine can last anywhere from a few minutes to several hours. The aura symptoms, such as visual disturbances, sensory changes, language difficulties, and motor disturbances, typically occur during the aura phase of the migraine and can last for about 20 to 60 minutes.

It's essential to note that the duration of the aura phase can differ among individuals. Some people may experience shorter episodes, while others may have longer-lasting aura symptoms. Additionally, the total duration of a silent migraine episode, including the aura phase and any associated symptoms, can extend beyond the duration of the aura phase itself.

If you experience silent migraines or any other type of migraine, it's essential to keep track of the duration and frequency of your episodes and discuss your symptoms with a healthcare professional. They can provide proper evaluation, diagnosis, and guidance on managing and treating your migraines effectively.

Silent Migraine and Anxiety

There appears to be a link between silent migraines and anxiety. Stress and anxiety are well-known triggers for migraines, including silent migraines. Furthermore, experiencing silent migraines can lead to anxiety and worry about when the next attack might occur, creating a cycle of stress that may contribute to more frequent episodes. There are several factors that suggest a potential link.

Shared Triggers

Both silent migraines and anxiety can be triggered or worsened by stress and emotional factors. High levels of stress can lead to physiological changes in the body, potentially contributing to the onset of both conditions.


There are similarities in the neurotransmitters involved in migraines and anxiety. Serotonin, for example, plays a role in mood regulation and is thought to be implicated in both conditions.

Central Nervous System Dysfunction

Both silent migraines and anxiety involve abnormalities in the central nervous system. Migraines are associated with cortical spreading depression, while anxiety is related to alterations in the brain's fear and stress responses.

Overlapping Symptoms

Some symptoms of silent migraines, such as cognitive difficulties, mood changes, and sensitivity to sensory stimuli, can resemble anxiety symptoms, leading to potential confusion in diagnosis.

It's important to recognize that not everyone with silent migraines will experience anxiety, and vice versa. Moreover, the presence of anxiety does not guarantee the development of silent migraines. Both conditions are complex and can vary significantly among individuals.

If an individual suspects a connection between silent migraines and anxiety in themselves or someone else, seeking medical evaluation is crucial. A healthcare professional can provide a comprehensive assessment, make an accurate diagnosis, and recommend appropriate management strategies for both conditions.
