There is this person I keep seeing on TV. Every time this person utters a word they accentuate their speech with hand gestures. My initial thinking is that this person is delusional but my question is as follows. Does such an individual exhibiting this behavior have a pathological disease? If so, can you name the disease? Extra points if there is a woman involved.
Every word, eh? Does this gesture resemble a hand puppet talking?
Exactly what kind of gestures are you talking about?
They’re Italian. 
Which person are you talking about?
I can think of one who constantly moves one hand and forearm up and down (and occasionally sideways) while speaking.
I can think of another who constantly moves one arm in a back-to-front arc, ending in a downward pointing/jabbing motion while he speaks.
Both movements are striking and, well, repetitive.
Am I getting warm?
No. Delusions are beliefs. Unless she’s whacking away imaginary birdies, it’s not likely she’s hallucinating either.
Hold a conversation with someone you know and mimic this person the best you can, sometimes this will give you a clue. It may only happen while making statements so try to mimic exactly waht is going on.
Either Italian or someone who often converses with persons who are hard of hearing.
Does he have really small hands?
I don’t quite get the OP. Are you trying to get us to guess something you think you already know the answer to, or are you genuinely curious about whether this person has a disease?
Italian!
You can’t just say linguine… You must hold your hands out, pinch your thumbs and index fingers together, and wave your hands up/down when at the same time saying linguine with an Italian accent.
Here are some lessons…

Well, if they’re on TV there should be a name and some videos we could watch.
People accompany their words with gestures all the time, and there is the gestural theory about human language development. It’s possible gesturing and vocal speech evolved together.
I like watching this guy’s hands while he talks. They never stop moving.
Could the person be signing to deaf viewers while at the same time speaking aloud to those with normal hearing?
I don’t know why you want me to name it, but I’ll oblige. I name it Bartolomeo.

We Jews do this too. The joke “I wanted to tell them! But how could I talk with hands tied behind my back?” appears in our joke books as well.
Certain people just talk with their hands.
