Negative Thinking Speeds Up Brain Decline and Raises Dementia Risk by Debbie Hampton

You'll  have to stop negative thinking patterns, like rumination and worry.

Anxiety and depression are also culprits.  All these can be solved if your doctor has EXACT STROKE REHAB PROTOCOLS  leading to 100% recovery. This is all your doctor's responsibilty. Don't let her/him weasel out of that responsibility by quoting this craptastic saying:'All strokes are different, all stroke recoveries are different'. 

Although I guess you might be allowed to have negative thoughts against your doctor for not being prepared to get you 100% recovered.
