The Headache and Epilepsy Center of Arizona – Scottsdale

The Headache and Epilepsy Center of Arizona is a partner of The Insomnia and Sleep Institute, where Dr. Vimala Sravanthi Vajjala focuses on treating patients for epilepsy, facial pain, and headaches—all of which can negatively affect sleep. Neurology and sleep are intertwined. Sleep deprivation and lack of quality sleep impacts the brain’s normal function in a myriad of ways, such as causing problems in vision, memory, pain control, seizure control, and more. If you don’t get enough quality sleep, whether from untreated sleep apnea (which is very common) or another cause, your risk of memory issues, stroke, seizures, and headaches drastically increases.

Poor sleep quality can trigger and aggravate chronic headaches, including migraines. In turn, all kinds of headaches as well as facial pain can be a catalyst for insomnia and worsen sleep quality. The American Migraine Foundation estimates that up to 75 percent of American adults with chronic pain conditions, particularly migraines, also struggle with insomnia. Sleep is a popular tool to temporarily relieve headache, migraine, and facial pain, but can lead to a vicious cycle of staying in bed too long, sleeping during the day, and ultimately worsening insomnia by trying to use sleep as a “treatment” for migraines.

Seizures can often present as a type of sleep disorder, such as dream enactment behavior or sleep talking. However, in these instances, what is occurring are nocturnal seizures—sometimes due to epilepsy. There has been an association between sleep and epilepsy dating back to ancient Greece. By the nineteenth century, it was found that around 20 percent of people who experienced epilepsy seizures did so exclusively during sleep. Various sleep stages, such as REM and non-REM sleep, can either activate or inhibit epilepsy episodes. The relationship between headaches, seizures, and sleep is a complex one that requires unique experts—which are available to patients at The Insomnia and Sleep Institute of Arizona.

“Working with the team at the institute and especially working with Dr. Krietsch has been an absolutely amazing life-changing experience. If someone had told me I’d be sleeping through the night AND getting up at 5:30 am every morning a few months ago… I would have told them they were crazy. My life is 100% better, I am keeping the institutes cards on hand and have handed them out to people who say they have insomnia.”

Treatments and Experience

Quadruple board-certified in Neurology, Clinical Neurophysiology, Headache Medicine, and Epilepsy, Dr. Vajjala’s years of expertise can help you address pain rooted in neurological issues. Dr. Vajjala is one of just circa 750 board-certified headache specialists in the country and even a smaller number of board-certified headache specialists in the country that also completed formal fellowship training in headache and facial pain. Her particular passions include treating epilepsy and migraines in women, autoimmune epilepsy, posttraumatic headaches, and cluster headaches. Some of Dr. Vajjala’s many skills include trigger point injections, nerve block injections, and botulinum toxin injections for headaches, as well as some other indications such as spasticity, cervical dystonia, and blepharospasms.

Associating sleep quality with headaches and seizures is nothing new. Aristotle suggested over 2,000 years ago that seizures and dreams, both viewed as altered states of consciousness, allowed the soul to disassociate from the body and prophesize the future. While that particular theory has long been debunked, it is clear that humans have long been aware of the relationship between seizures, pain, and sleep. Today, we know that sleep impacts the entire body and the quality of sleep is evident in all of our tissues. This means that sleep impairments can have vast and serious effects on neurological, immune, cardiovascular, and metabolic health. This means poor sleep can lead to higher risks of developing various neurological disorders, including epilepsy, stroke, neuromuscular disease, neurodegeneration, and movement disorders. When you improve your sleep, you improve headaches and facial pain while also decreasing risks and occurrences of seizures. It all starts with connecting with sleep professionals who are the leading expert in their field.

Neurology Treatments

Available at our Scottsdale clinic (a partial list)

Headaches and Migraines

Our neurologist employs a multifaceted approach to treat headaches and migraines, recognizing the diverse underlying causes and individualized patient needs. The initial step typically involves a thorough evaluation to pinpoint triggers and rule out any concerning neurological conditions. Lifestyle modifications, such as identifying dietary triggers, optimizing sleep patterns, and stress management, are often recommended. Medications tailored to the specific type of headache are frequently prescribed, ranging from pain relievers for mild episodes to preventive drugs for chronic sufferers. Botox injections and nerve blocks may also be considered in certain cases. Behavioral therapies, like cognitive-behavioral therapy and biofeedback, are beneficial for some patients in managing the psychological aspects of chronic pain. Neurologists aim to provide comprehensive care that enhances the quality of life for those enduring the debilitating effects of headaches and migraines.


Our neurologist, Dr. Vajjala, employs a comprehensive approach to effectively manage epilepsy and seizures, recognizing the importance of tailoring treatment to the unique needs of each patient. Diagnosis often involves detailed neurological evaluations, brain imaging, and electroencephalograms (EEGs) to pinpoint the seizure’s origin and characteristics. The primary treatment strategy usually revolves around antiepileptic medications, carefully chosen to control seizures while minimizing side effects. For some individuals with drug-resistant epilepsy, neurologists may explore surgical options like resective surgery or neurostimulation devices such as the vagus nerve stimulator or responsive neurostimulation. Lifestyle modifications, including stress management and adequate sleep, are also crucial components of treatment. We work closely with our patients to create personalized seizure management plans that aim to optimize their quality of life and minimize the impact of epilepsy on daily activities. Additionally, ongoing monitoring and adjustments to treatment plans are essential for long-term seizure control and overall well-being.
