That cliche... things aren't always as they seem... keep that one in the back of your mind because you'll test its validity a couple times before the movie is over.
There are some clever moments of violence, but I'd hesitate to go so far as to tell you that that was a reason to actually check out Dementia. There's a general feeling of disorientation that doesn't come from swirly whirly cameras or strange focus pulls. I can appreciate that. You feel as confused as our protagonist because of what the director decided to show you and hide from you during moments of dementia. It's nice to not have to be an audience at a drive-in movie theater in the 1960's during a "freak out". Simplicity, that can be a virtue too.
Dementia is shot well though I'd say primarily you're watching this to enjoy the story and not the effects or appreciation of the cinematography. This is definitely what we have come to expect from IFC Midnight, and is a good fit for the Scream Factory/IFC partnership. Definitely give this one a try.

From Scream Factory:
A disabled war veteran is in bad hands when his family hires the live-in nurse from hell in this intense psychological shocker. George (Gene Jones of The Hateful Eight and The Sacrament) is an aging ex-soldier haunted by memories of Vietnam and struggling to reconnect with his estranged son and granddaughter. But when he suffers a stroke and is diagnosed with dementia, George is left in the care of Michelle (Halloween's Kristina Klebe), a seemingly sweet nurse with a disturbing dark side. At the mercy of a psychopath with a hypodermic needle, George becomes a prisoner in his own home, caught in a sadistic game of cat and mouse as brutal as anything he experienced in Vietnam. In his feature debut, director Mike Testin masterfully keeps the tension mounting – until it explodes in delirious violence.
