Dr. Frederic A. Mendelsohn MD's Expert Contributions
My sister is having a lot of headaches that aren't subsiding with any medicine. What should we do?
If she has not seen a neurologist yet I suggest she does so. Neurologists are familiar with some treatment options that many family docs do not. READ MORE
My friend recently died of a stroke, could it have been prevented?
I really do not have enough information to answer your inquiry, however, allow me to offer some hopefully illuminating information regarding strokes. There are three basic causes of stroke-hemorrhage, emboli, and ischemia. Hemorrhagic strokes may be caused by severe hypertension or by rupture of an aneurysm. The latter are with an individual from birth and may hemorrhage at any age, including in people in their twenties. They rupture without warning and are often fatal, taking life at times before the patient presents to hospital. Embolic strokes are sometimes associated with atrial fibrillation or heart valvular disease, and ischemic strokes are caused by a blockage in arterial circulation. The latter we believe is often caused by chronic hyperlipidemia as well as chronic elevations in blood glucose as well as chronic hypertension. For the vast majority of stroke victims, the presenting symptom of a stroke is...stroke. READ MORE
Within how many hours of getting a stroke should one be admitted in the hospital?
All stroke patients should be evaluated ASAP. READ MORE
My sister is having a lot of headaches, which are not subsiding with any medicine. What should we do?
Assuming she has had proper diagnostic testing and all are normal, she most likely is suffering from migraine headache since the vast majority of headaches are migraine based. If migraine meds are ineffective, Botox may help. READ MORE
Why is my mother complaining of hand shivering?
It depends upon the characteristics of the tremor. Benign tremors are typically more severe on intention whereas Parkinson Tremors are typically more noted at rest and look like the individual is rolling a pill between the finger tips READ MORE
Why does my head have pain around noon?
It is difficult to respond to your inquiry without more detailed history, however due to the timing of your symptomotology dietary influence is a possibility. If you are a migraineur there are several foods that may trigger your headache ie. caffeine overuse or withdrawal. READ MORE
Can autism ever be cured?
I know of no cases of “cure” however early intervention has proven to be very effective for many children, helping them to successfully integrate. READ MORE
Is nerve pulling common in diabetic patients?
I am sorry. I do not know what you mean by nerve pulling. READ MORE
Can taking painkillers for a long time impact the CNS?
At this time we have no evidence that short term use of analgesics is harmful to the CNS. Word of caution however,it has only been recently discovered that proton pump inhibitors like Prilosec are associated with dementia. READ MORE
What are the tests to confirm Alzheimer’s disease?
The diagnosis may be suspected by clinical observation and patient history. MRI, CT, and PET scans help to confirm the diagnosis. There is a genetic test as well, however, only about 20% of patients with alzheimers are positive for the genetic abnormality. Neuropsychiatric testing may prove useful as well. READ MORE
I have spasms and pins and needles sensation in my hand. Please help.
The most common cause of hand tingling is carpal tunnel syndrome, which is due to compression of the median nerve in the flexor surface of the wrist. Another possibility, however, is a problem in the cervical spine. While these symptoms may represent a relatively benign problem, I recommend that you seek a formal neurological consultation. READ MORE
What is the possible treatment for vertigo?
Assuming that the vertigo is secondary to a disorder in the inner ear (semicircular canal) and not the brain stem, vertigo can be managed by a physical therapist trained in vestibular rehabilitation. In some cases, a potassium sparing diuretic called Diamox may be helpful. READ MORE
MRI brain shows some white spots. What does it mean?
White spots may be seen in several benign conditions such as migraine headache, however if in association with hypertension and diabetes, they may be representative of "mini strokes" which are often "silent" without symptoms. White spots may also indicate a demyelinating process such as multiple sclerosis. Some forms of dementia may also present with white spots on MRI. READ MORE
