Following a head injury in a Road Traffic accident I was referred for an MRI, due to dificulties with my memory, concentration and headaches, coldness and numbness in my limbs, all within 2 months of the accident. My initial MRI feedback stated "hyper signal intensities, post traumatic changes - contusion."

A follow up appointment with a Neurologist and it was further mentioned that there were "dots in the white matter on your brain". This was followed with the claim that is was normal for this to happen with age, perhaps not related to the accident, and not the evdience of any pathology. I am 31.

Why would these suddenly appear, is the doctor right to suggest it is not related to the injury? How can these just appear with age? If they are normal for a 31 year old, why would they be mentioned in the MRI results?

Does anyone have any advice on how I can improve my concentration and reduce the numbness since it appears further help from the NHS neurology route will not be forthcoming.
