"Stroke" also more technically referred to as CVA (Cerebral Vascular Accident) is divided in a couple of ways.
First, more generally, you have embolic/thrombotic versus hemorrhagic. Embolic/Thrombotic involves clots (either thrown off of the Heart Valves - most common, or from elsewhere, or formation of said clot within the brain itself), whereas hemorrhagic, as the name implies, involves a bleed in the brain.
Secondly, strokes are divided based on the duration of the sequelae:
TIA (Transient Ischemic Attack) - Stroke effects last less than 24h
RIND (Reversible Ischemic Neurologic Deficit) - Effects last longer than 24h
Stroke (Evolving or complete) - Some perminent sequelae will result.
You can also classify them by anatomical location or etiology, but that is a few pages unto itself.
Fetzer does appear to speak out of one side of his mouth, and at times seems to have a bit of a tremor and head tilt.
This may have been due to a stroke, or may not. Cervical dystonia can cause such a tremor and/or head tilt, and is often benign and unrelated to CVAs. As for the lip issue, a couple of things... If his eye on the same side works fine from an opening and closing pov, than stroke would be more likely than Bell's Palsy, as Bell's usually involves both distributions of the Facial Nerve (Cranial Nerve seven) and hence their eye would not close properly along with the lip on that side remaining flacid/unmoving. As well, it may simply be a tic or habit he has formed...
The Right side (her right side) of this woman's face is the NORMAL side. This is Bell's palsy. Notice how on the effected side (her left) she cannot smile OR close her eyes, as opposed to her right (uneffected side) where she can do both. This is how we distinguish it from the sequelae of a stroke, which in almost all cases only effects either the eye OR the mouth, not usually both.
As Gravy has said, rather then speculate, the only way to know for sure, is to ask the man.
