Brief Answer:
Migraine headache

Detailed Answer:
Thank you for asking

I read your question and i understand your concern. These symptoms are of a simple migraine headache. No stroke or any aneurysm with any past history is likely.
A migraine headache can cause intense throbbing or a pulsing sensation in one area of the head and is commonly accompanied by nausea, vomiting, and extreme sensitivity to light and sound.

Migraine attacks can cause significant pain for hours to days and be so severe that all you can think about is finding a dark, quiet place to lie down.

Some migraines are preceded or accompanied by sensory warning symptoms (aura), such as flashes of light, blind spots, or tingling in your arm or leg.

Medications can help reduce the frequency and severity of migraines. If treatment hasn't worked for you in the past, talk to your doctor about trying a different migraine headache medication. The right medicines, combined with self-help remedies and lifestyle changes, may make a big difference.

Headaches with difficulty recognizing words however needs evaluation. Migraines can't be cured, but doctors will work with you to help you manage your condition.

A variety of medications have been specifically designed to treat migraines. In addition, some drugs commonly used to treat other conditions also may help relieve or prevent migraines. Medications used to combat migraines fall into two broad categories:

Pain-relieving medications. Also known as acute or abortive treatment, these types of drugs are taken during migraine attacks and are designed to stop symptoms that have already begun.
Preventive medications. These types of drugs are taken regularly, often on a daily basis, to reduce the severity or frequency of migraines.
Choosing a strategy to manage your migraines depends on the frequency and severity of your headaches, the degree of disability your headaches cause, and your other medical conditions.

Some medications aren't recommended if you're pregnant or breast-feeding. Some medications aren't given to children. Your doctor can help find the right medication for you. Avoid following dietary triggers for migraine headache.

Alcohol - Particularly wine and beer
Caffeine overuse or caffeine withdrawal
Chocolate
Aspartame - eg, NutraSweet and Equal
Monosodium glutamate (MSG) - May be found in Asian food, canned soup, frozen or processed foods, and the seasoning product Accent
Fruits - Citrus fruits, bananas, avocados, and dried fruit
Nuts - Peanuts, soy nuts, and soy sauce
Tyramine, a biogenic amine that accumulates in food as it ages, may provoke migraine. Sources include the following:

Dairy - Aged cheese
Meat - Bacon, sausage, luncheon meat, deli meat, pepperoni, and smoked or cured meat
Pickled foods
Heavily yeasted breads - Eg, sourdough
Vinegars - Especially wine vinegar
Some types of beans
Nutraceuticals shown to be effective in randomized clinical trials include the aforementioned vitamin B2, CoQ-10, magnesium, and butterbur (Petadolex)

I hope it helps. Take good care of your son and yourself and dont forget to close the discussion please.
