Hello !
I read your question and understand your concern. In my opinion he is suffering for hyipersomnia. It is more common in
thalamic stroke. Unfortunately there is not a curable therapy to this problem. I would give some advises to try to regulate his sleep cycle:
-Sleep a few hours longer at night to avoid excessive sleepiness during the day.
-Exercise daily in the morning or early afternoon, if possible.
-Engage in enjoyable activities that require your full attention, such as spending time with friends, writing letters, or playing with a pet.
-Try to go to sleep and wake up at the same time every day.
-Get out of bed and stay out of bed until bedtime.
-Avoid foods that make you sleepy and heavy meals during the day.
-Avoid alcohol and caffeine.
I would also try
Modafinil , which is a drug effective in primary hipersomnia. This drug must be prescribed under a
neurologist prescription.
Hope to have been helpful!
Best wishes, Dr. Abaz Quka
