Scientists have examined the effects of language on categorical color perception -- the idea that color perception is affected by how it is described in language -- with behavioral research. Meanwhile, other scholars have looked into this phenomenon using neuroimaging techniques in an attempt to get a better look at the neural processes underlying these results.
A thunderclap headache. Post-partum cerebral angiopathy. Sub-arachnoid hemorrhagic headache. Posterior reversible encephalopathy. Primary and benign angiopathies of the central nervous system. Call-Fleming syndrome. I am not throwing the dictionary at you. These are all sudden onset headaches resulting from changes in the flow of blood in cerebral arteries. Recent opinion tends to aggregate all these kinds of headaches under a common term, Reversible Cerebral Vasoconstriction Syndrome (RCVS).
Excess food intake makes you fat. High calorie foods make you gain excess fat. Excess carbohydrates and saturated fatty acids get taken up by fat cells and get converted into fatty acids stored within them. This is what we know of the straightforward relationship between diet and obesity. Yet, the relationship between food choices and obesity is not so linear or short-term. Food choices and obesity have a more complex interdependence.
In recent years, clinicians have utilized a somewhat surprising tool to treat their patients with refractory epilepsy-diet. The majority of people with epilepsy can become free from seizures with the use of antiepileptic medications, but in about 20-30% of people with epilepsy, medications fail to completely control their symptoms. Clinicians and researchers have found the ketogenic diet is an effective way to treat these patients; it is at least as successful as the most recent anticonvulsant drugs designed to treat refractory epilepsy. Researchers have also started exploring the therapeutic potential of the diet in other neurological conditions, including Alzheimer’s disease, Parkinson’s disease, and Amyotrophic Lateral Sclerosis (ALS), among others.
