DEAR DOCTOR. COCKROACH: Periodically, I undergo from kaleidoscope imaginative and prescient the place my peripheral imaginative and prescient within the excessive proper or left eye looks as if I am trying by damaged glass. It began about 5 years in the past, once I was 65. After about 10-15 minutes, it goes away. My head by no means hurts. It does not hinder my view aside from being very annoying. I spoke with two internists they usually each prompt that I see an ophthalmologist. The attention physician mentioned there’s nothing to fret about.
Pricey reader: Sudden imaginative and prescient adjustments in a 70-year-old man ought to elevate issues a couple of blockage within the arteries of the attention; nevertheless, the sample you’re describing sounds extra more likely to me to be a migraine aura. Some individuals can develop a migraine aura with out a headache. Many individuals describe an “patchy” or “shiny” look, making the prognosis of migraine aura extra probably. Maybe that’s much like what you name “kaleidoscopic imaginative and prescient.”
If the ophthalmologist carried out an entire examination and located nothing, it’s a good signal. As an internist, I am going to take the chance to verify your threat of growing blocked arteries is as little as attainable, together with a test on blood strain, smoking, ldl cholesterol, weight loss program, train, and stress.
DEAR DOCTOR. COCKROACH: My cousin was in his 40s when he died of a mind tumor, greater than 10 years in the past. After having comparable signs, my different cousin, her older sister, who’s in her 60s, simply had surgical procedure to take away a cancerous mind tumor. Is it attainable that that is hereditary? Neither of them had youngsters, however they’ve an older brother. Must you get examined? Is that this one thing you might be examined for?
Pricey reader: Many cancers are inherited, some greater than others. Major mind cancers are uncommon and there are differing kinds. A main mind most cancers is one which begins within the mind, versus when most cancers in a unique space of the physique spreads to the mind, which is far more frequent. Many cancers that may metastasize to the mind are inherited.
Two of the commonest varieties of main mind cancers are astrocytomas and glioblastomas. A latest evaluate discovered that astrocytomas have a household part, however glioblastomas don’t. Individuals with a household historical past of astrocytomas are 4 occasions extra more likely to develop one; nevertheless, it might nonetheless be uncommon to develop mind most cancers even with a household historical past.
The best threat of mind most cancers is ionizing radiation, like that which an individual would obtain with radiation therapy for childhood most cancers. Nevertheless, within the 1950s, radiation was used to deal with pores and skin infections on the top, which has led to an elevated threat of mind most cancers in these handled. Nevertheless, your cousins should not sufficiently old for this sort of publicity.
There are some uncommon genetic circumstances that enhance the danger of mind tumors, together with sort 2 neurofibromatosis and sort 1 a number of endocrine neoplasia.
For the reason that probability of growing a mind tumor is small, even with a household historical past, I do not assume I’d advocate screening in your brother. I appeared for any research that may be in progress to check if there may be any profit in screening; sadly, I did not discover any on Clinicaltrials.gov.
