I am at present taking galantamine 16mg and mirtazapine 30mg for my Alzheimer's, I was on citalopram 20mg. Since starting the mirtazapine my night terrors have become worse but my hand shaking and tremors have lessened ,so I asummed with less shaking it must suit me better. I wasn't sleeping so that's why the change of anti depressants . Just wondered if the nightmares / night terrors are just a natural progression of the Alzheimer's or not , anyone else experience these ?
