My partner has had Vas.Dem. for nearly 4 years.He has been suffering with urine infections for the past 8 weeks. Finally cleared & now he is crying all the time. I thought it was just when I went shopping but it's even when I am here.Does anyone know if it's just a phase or will I need to take him to a doctor? He is sundowning as well & has started to take all his night clothes& incontinence pad off in the middle of the night
