Conviction for theft by a caretaker from an elder is affirmed over claims that: 1) there was insufficient evidence to support conviction for theft based on theory of larceny, as the victim, a 68-year-old man suffering from cognitive impairment from Parkinson's disease and the medication taken to treat the disease, consented to her taking his money to buy a new sport utility vehicle; and 2) the trial court erred by instructing the jury in accordance with Penal Code section 1127g that a witness with a cognitive impairment is not any more or less credible than any other witness.
