Hi,
The most probable cause of the symptoms that you have mentioned is Multiple sclerosis. Other causes could be brain tumour or Amyotrophic lateral sclerosis. Multiple sclerosis is a demyelinating disease that affects the nerves of the brain and spine. The symptoms are- brain fog, memory problems, numbness and tingling, headaches, muscle weakness and many others. Please go for the CT scan. MRI is more detailed and accurate. Please consult a neurologist for the diagnosis and treatment. Hope this helps you. Take care and regards!
Thanks for your input. I am still waiting on my appt time for the CT scan and called today to report the new symptom of tingling and numbness. I am waiting to hear back on that as well.
