My neighbor has dementia and hoarding and is keeping me awake all night. Any suggestions?

She has hoarded herself out of much of the bungalow, and lives and sleeps in the one room, the bedroom wall which adjoins mine. I have had mice in my home due to the state of her property. She sleeps all day and gets up at around 9pm at night rummaging around her hoard, moving things, things crashing and banging to the floor, and then she goes to bed around 9 - 12pm the next day. Her curtains are closed 24/7. She doesn't wash, and she doesn't eat very much she is thin, frail and dirty, and the stench of dogs feces, urine and rotting debris from her property is putrid. When her family does come round they take her out, they do not spend much time in there at all, and leave her dogs locked in the small dark hall for hours, sometimes days and they suffer separation anxiety, and so constantly howl.

I spoke to the family numerous times but they ignored me and ended up changing their telephone numbers. After 18 months I went to my Landlord, social services and the Alzheimer's society. This was when her 50 year old cannabis smoking son came to stay, which then added another problem, my home stinks of cannabis most of the time. The noise recorder went in and she was served a Community Protection Notice, which has already been breached, social services were trying to gain access but the son wasn't allowing her to open the door. Then 5 months later came the lockdown due to Covid-19. I am at the end of my tether, the son is going out most of the afternoon, and returning to the bungalow at night, then sits up all night with his mother while she makes noise all night, but doing nothing to stop her. My bed has been in my living room for 13 months now as it is the furthest room in the bungalow from the adjoining wall. However, the noise she makes is loud, climbing and waded over stuff and slamming the internal doors, it is a compulsive sound, a behaviour she cannot control, she also gets nasty, and has been abusive to me, and she has threatened to attack her son with a knife. I frequently hear her on her mobile phone in the garden accusing family members of stealing money or money going missing from her account, she also thinks people are stealing things from her home and garden. She has already been verbally abusive towards one of my neighbours (this was before I moved here), for which the police were called, as she believed her husband had moved in with her, even though her husband left 10 years ago due to the hoarding. I often see black smoke coming out of the kitchen window during the early hours of the morning, where she has forgotten what she is doing and has gone on to something else. Despite all this social services and my Landlord will not breach the lockdown to take action, even though her own family are not adhering to the lockdown, neither are they safeguarding my neighbour. As a result of lack of sleep, I am sinking into a depression, my asthma is affected by the constant stench of cannabis and I'm at the end of my tether.
