My grandma lives with my grandpa. Over the past few months (around 3), we've found wine bottles hidden under beds, in night stands, or in her quilting room. Sometimes the bottles are open, other times not. We began marking the liquid to see how much was being consumed during specific time periods. Most often, very little to no wine has been consumed. Other times, a significant amount of wine is gone. My grandma has a two story house, and has trouble walking easily. This is a bizarre development to think she's started drinking heavily and can still manage to navigate the stairwell and not be ill from the amount of wine she'd have to be consuming at times. I have read that people with dementia sometimes hide things out of fear etc, and I'm wondering if hiding alcohol is something common? We confronted her and her reaction was anger. I'm not sure the specific answer she gave were the truth or if she were just reacting to the situation we put her in with an 'intervention' of sorts. Could she be going for a drink of wine, forgetting she had a drink of wine, and then going back for a drink of wine? I am so confused if this is a dementia problem, or an alcohol problem.
