Distinguishing normal aging from early dementia can be difficult, but there are clues that can help. Neurologist Gregory E. Cooper, M.D., Ph.D., chief of adult neurology and director of the Norton Neuroscience Institute Memory Center, answers the most commonly asked questions. What are the differences between normal cognitive aging, mild cognitive impairment and dementia?According to…
Norton Healthcare is offering a professional, structured observation program for flight nurses, paramedics, EMTs and first responders to enhance their knowledge of stroke and learn about state-of-the-art treatment and interventions. Recognizing the key role of EMTs and paramedics in stroke care is a priority because they are the first people who interact with the stroke…
[vc_row][vc_column][vc_column_text] Clinical challenge Radiation necrosis of the brain causes debilitating headaches, recurrent seizures, focal neurological deficits and subcortical neurocognitive slowing. Radiation necrosis occurs in about a fifth of patients who receive stereotactic radiation therapy (SRT) or stereotactic radiosurgery (SRS). Radiation therapy is increasingly used as a noninvasive treatment for benign diseases such as arteriovenous malformation…
A stroke occurs when blood flow to the brain is disrupted, either when a blood vessel is blocked (an ischemic stroke) or when a blood vessel bursts (hemorrhagic stroke). The brain uses constant blood flow to provide necessary oxygen and food supply. Without this flow, the brain cells begin to die. Once brain cells die,…
The patient A 27-year-old female presented with five months of progressive quadriparesis and paresthesias affecting both upper and lower extremities.

Dementia is an umbrella term that includes a range of symptoms associated with cognitive decline. Perhaps one of the best known and most common types — Alzheimer’s dementia — represents 60% to 80% of all dementia. It’s characterized by memory loss and, from a biological perspective, amyloid plaques, neurofibrillary (tau protein) tangles and neurodegeneration, which…
Time saved is brain saved when it comes to stroke care. “Stroke is one of the leading causes of death in the U.S,” said Shervin R. Dashti, M.D., Ph.D., endovascular neurosurgeon and spine surgeon at Norton Neuroscience Institute. “Three-quarters of a million strokes per year, many million stroke survivors, and it’s one of the leading…
Additional data could lead to stronger guidelines extending the tPA window for ischemic strokes beyond the current 4½ hour limit in coming years, according to a Norton Neuroscience Institute stroke specialist. A common scenario faced in stroke centers is a patient who awoke with a deficit but doesn’t know when they had a stroke. The…
Patients who are cognitively normal but have a family history or other concern about developing Alzheimer’s may be eligible to participate in a study looking at whether an investigational drug can slow or prevent the disease. Norton Neuroscience Institute is one of 230 centers around the country participating in the phase 3 trial of a…
When are headache symptoms consistent with migraine or red flags of a condition warranting urgent or emergency medical attention? Migraine occurs in a recurring pattern and can be diagnosed clinically, without MRI or other tests, according to Brian M.
