- Sleep Medicine
A sleep medicine specialist is specially trained in diagnosing and treating disorders involving sleep.
Sleep disorders such as sleep apnea, restless leg syndrome and insomnia are very common and can often cause other serious health issues, such as depression, asthma, and migraines. Sleep medicine specialists often work in sleep centers where they observe a patient while sleeping and monitor brain waves, behavior, and vital signs in order to identify the causes of sleep disturbance, or an inability to sleep (insomnia).
Sleep medicine specialists treat patients through advising on sleep hygiene, providing cognitive behavioral therapy, using light therapy, or medical sleep aides.
A neurologist is a physician who diagnoses and treats disorders of the nervous system which is comprised of the brain, spinal cord and nerves. These doctors do not perform surgery, but refer patients to neurological surgeons when they determine that surgical intervention is necessary.
Some of the conditions that neurologists diagnose and treat are epilepsy, aneurysms, hydrocephalus, Parkinson's disease, multiple sclerosis, stroke, spinal disc herniation, and spinal disease.
In addition to using diagnostic tests like MRI, CT scans, EEG and EMG, neurologists also employ neurological testing to gauge muscle strength and movement, balance, reflexes, sensation, memory, speech, and other cognitive abilities.

I saw Dr. Dengler after I was admitted to Johnson City Medical Center in Johnson City, TN. After many tests it was determined that I had a TIA (mini stroke). I did not see Dr. Dengler until after the test results came back, he visited me in my hospital room and prescribed Crestor and a daily baby aspirin. When I went to his office for a follow up appointment there was no nurse in the room with us, he basically asked how I was feeling, asked me to touch my nose, stand up, sit down and sent me on my way.
Poor office staff. Can't be trusted to do what they say they will do. Made arrangements to have botox injections. My insurance was ready to allow me to buy Botox from pharmacy take to Dr. Dr. office agreed to do it that way but insisted they would order it on my Rx plan. I verified they received med. went to appointment Dr. said it was drug they ordered in fact commented, we just replenish our stock with ordered meds. Imagine my surprise when they bill me for drug three months later . Tried to negotiate after all it was their mistake. Office manager sent me a letter saying it was my bill and I had to pay it. I have it in writing they agreed to payments I paid the first one at the front window. Sent in another the first of this month. Now they have returned it. What more can I do.
Never spends more than 5 min in my room last time i was in his office i asked about my ct scan i had done and he lied about the results i dont think he has ever even looked at my profile i was supposed to have another apt last month and they failed to schedule it because of this my prescription didn't get refilled and he won't fill it till i come back in
Insursnce required some forms to be filed, weeks have gone by and nothing has been sent in or filled out.Now he is out of town and there is no back-up to get the paperwork completed
