At Tampa Bay Neurology and Sleep Medicine, Dr. Arun Rajan is a board-certified, fellowship-trained neurologist who specializes in treating epilepsy. He sees children and adults from 9 years old and up. A neurologist diagnoses and treats disorders of the nervous system: the brain, spinal cord, nerves, and muscles.

Epilepsy is a disorder that is caused by a surge of abnormal nerve signals in the brain. Repeated seizures are the main symptom of epilepsy. There are several different types of seizures.

In many cases, the cause of epilepsy is unknown. Epilepsy can run in families and may occur as a result of a genetic disorder or an acquired brain injury, such as a trauma or stroke.

Treatment for epilepsy involves medications, dietary changes, surgical procedures, or a combination of treatments to reduce and prevent seizures. With treatment, some people can become seizure-free.



Among the most common disorders of the nervous system are headache disorders and it has been estimated that almost half of the adult population have had a headache at least once within the last year, according to the World Health Organization. Headache disorders are divided into primary disorders and secondary disorders. In primary headache disorders, there is no obvious underlying cause. On the other hand, secondary headache disorders can be caused by or occur secondarily to an extensive list of other conditions and one of the most common of those is medication-overuse headache. These disorders vary in incidence, prevalence, duration, and consequent impact. In turn, this imposes a substantial burden on headache sufferers and on society.

Headache disorders:

Headache disorders are typically most troublesome in the productive years of one’s late teens to 50s. Therefore, they are a public-health concern given the associated disability and financial costs to society due to lost working hours and reduced productivity. Yet, most headache sufferers rely merely on over-the-counter medications and do not receive effective care.

Headache disorders can be treated by Tampa Bay Neurology & Sleep Medicine after establishing an accurate diagnosis with patient education, simple lifestyle modifications, and probable cost-effective medications. When headache frequency and disability are high, preventative treatment medications are prescribed. There are several classes of medications that are typically prescribed including but not limited to:

  • Antidepressants (amitriptyline, nortriptyline, & venlafaxine)
  • Anti-Epileptic Drugs (AEDs) (topiramate, gabapentin, & divalproex sodium)
  • Beta-Blockers (propranolol & metoprolol)
  • Calcium Channel Blockers (verapamil)
  • Calcitonin Gene-Related peptide (CGRP) Inhibitors (Aimovig, Ajovy, & Emgality)
  • Botox (onabotulinumtoxinA) Injections
  • Vitamins and Supplements (Magnesium, Riboflavin, Coenzyme Q10)

Pharmacological treatment of acute headache disorders include simple and combination analgesics, nonsteroidal anti-inflammatory agents (NSAIDs), ergot alkaloids, triptans, antiemetics, and CGRP inhibitors.

If you are troubled by headaches, it is vital to seek appropriate treatment from a neurologist. To schedule an appointment with Tampa Bay Neurology & Sleep Medicine, please call us at (813) 564-0140 or request one online.

The word epilepsy is from the Greek verb, epilamvanien, which means “to be ceased” or” to be taken hold of”.

Today, a large number of clinical phenomena are recognized as epileptic seizures, some of which are poorly understood. Epilepsy and epileptic syndromes are broadly divided into idiopathic and symptomatic disorders.

Idiopathic epilepsies: These type of epilepsies are not associated with brain lesions. There are not associated with mental disorders and usually respond well to medications. Genetic factors may be important and epilepsy manifestations may be age-related.

Symptomatic epilepsies: These are epilepsies in which seizures on the consequence often identifiable lesion in the brain are some other specific cause.

Incidence: Epilepsy affects about 2-5% of the population with the incidence fluctuating between age groups. Epilepsy is more common in men.

More than 50% of epilepsies are classified as partial seizures, which are more bland and difficult to recognize. About 25% of epilepsies are generalized meaning it is accompanied by a convulsion in most cases.

  • Complex Partial Epilepsy
  • Generalized Epilepsy
  • Other epilepsies

Testing for epilepsy:

Routine EEG: This is usually performed as an outpatient in the office setting. The whole procedure takes about an hour with a recording time of about 30 minutes. A technician will perform the study. Tampa Bay Neurology and Sleep Medicine offers this service

Ambulatory EEG: This is performed as an additional testing in some patients in whom the initial EEG does not show any abnormality and if the suspicion for epilepsy is high. It is also performed in patient’s who are suspected of having breakthrough seizures without being aware of the events. This recording is usually done for 3 days and sometimes less. Tampa Bay Neurology and Sleep Medicine offers this service.

LTM: Long-Term Monitoring is usually performed as an inpatient for patient’s who are refractory to medications. This testing is performed in epilepsy centers. The purpose of this testing is to determine if the patient is a candidate for surgery. The surgical options include focal resective surgery, vagal nerve stimulator implant.

To help diagnose neurological disorders, Dr. Rajan will perform a comprehensive evaluation, and he may order diagnostic tests such as:

  • Electromyography (EMG) and nerve conduction studies (NCS)
  • Electroencephalography (EEG)
  • Ambulatory EEG for 24-48 hours with video recording
  • MRI – located in same building
  • Laboratory – located in same building

EMG and NCS are tests that help Dr. Rajan assess the health of muscles and the nerve cells that control them. NCS measures how well a nerve works while EMG measures how well a muscle works in response to electrical nerve impulses. Measuring the electrical activity in muscles and nerves can help detect the presence, location, and extent of muscle or nerve disorders, such as a herniated disc, amyotrophic lateral sclerosis (ALS), muscular dystrophy, or peripheral neuropathy.

Electroencephalography (EEG) records the electrical activity of the brain. This test is used to diagnose and monitor epilepsy, seizures, Alzheimer’s disease, head injuries, and sleep disorders. An EEG in the office provides only a 20- to 40-minute sample of brain activity, whereas an ambulatory EEG records seizure activity for an extended period of time (24-48 hours) while you are both awake and asleep.
