Hi,theres a Neuro-psychiatrist who is very-famous for his expertise in Spect-Scans.His name is Dr.Daniel Amen:Look it up on Google,you might be very interested in his Clinic.All the best John
Thanks so much for your question. First I want to say that I am not a neurologist and would like to give you my approach to your question regarding and physical exercise since I have been working with several patients with brain cysts.
The information in this comment it is not intended to diagnose or treat any condition and should never replace your visit with a neurologist.
Brain cysts are structures filled with fluids such as water, cerebrospinal fluid, or tissue among others. Regarding brain cysts there are also different types and symptoms and would vary on where the cyst is located. Generally speaking, brain cysts only become symptomatic, and thus problematic, when they experience a change in size. The main problem with brain cysts is the way they tend to block off the flow of cerebrospinal fluid in the brain.
In other words many people have brain cysts and they don’t even know it until they act up. Brain cysts are also found more commonly in young male patients younger than 15 years of age being present approximately in roughly 1% of the general population.
Regarding your really wise concern if your son should be engaging in martial arts may I say first that there is a general consensus that physical exercise is a positive effect in the patient since having a fit body is always important to carry your body. Moderate exercise is positive on your brain, muscles and spinal cord. However there is a general recommendation that contact or impact sports are not highly recommended. In other words it is not a total contraindication to participate in contact sports, however patients and their family or relative members should be carefully advised of the risk of a cyst when practicing impact or contact sports.
My suggestion is that for a more detailed information to your question please post the same question at Medhelp.org in the Brain, Pituitary & Skull Base Tumors forum. Dan Prevedello, MD, Neurosurgeon at OSU is answering tumor (and occasionally cyst) questions in the Brain Pituitary & Skull Base Tumors forum. I hope my answer was helpful
