Aphasia and Migraines: Understanding the Connection

Temporary episodes of aphasia, a condition characterized by difficulty in speaking, comprehension, or writing, can sometimes occur alongside migraine attacks. These episodes can be due to various factors such as migraines, seizures, or a transient ischemic attack (TIA). A TIA is a temporary event where blood flow to a part of the brain is interrupted, leading to a loss of function in that area that typically lasts from minutes to hours and resolves completely within 24 hours.

Understanding the Causes of Transient Aphasia

One theory behind the cause of transient aphasia involves an unusual electrical wave known as spreading cortical depression. This wave disrupts the normal flow of electrical currents among neurons in the brain. When this wave occurs, individuals not only struggle with recalling words, whether written or verbal, but also face cognitive challenges that can create a sense of “brain fog.”

Temporary aphasia can also be triggered by vasospasm, a condition where blood vessels in the brain constrict, leading to reduced blood flow. In certain cases, this can result in aphasia. Moreover, migraines can sometimes cause cerebrovascular accidents, or strokes, which can affect speech and language abilities.

Migraine-Related Aphasia: A Complex Diagnosis

Migraines can target specific parts of the brain, and this fact is often used to diagnose the condition. However, this does not rule out migraines as a cause of aphasia when it affects less common areas. While aphasia is not a common symptom of migraines, recurrent migraines in the same part of the brain can suggest migraine as the cause.

Impairment in the same part of the brain that comes and goes can also indicate migraines. Unfortunately, other organic brain issues such as scar tissue, tumors, or abnormal neuron discharges can also have the same episodic nature. Migraines can occur secondary to these organic problems. Therefore, MRI, PET scans, and EEGs may not show positive results unless the migraine is happening at the time of the tests. This can be frustrating for individuals seeking a quick diagnosis, but it helps to rule out other potential causes.

Conclusion and Further Reading

Understanding the connection between aphasia and migraines is crucial for both patients and healthcare providers. While some episodes of transient aphasia can be attributed to migraines, a comprehensive diagnostic approach is necessary to rule out other underlying conditions.
