The spider-like hallucinations are classic alcohol-withdrawl symptoms not directly associated with dementia or alzheimer's. This story is on a number of sites,

  Hallucinations are a part of dementia for some people. Tactile hallucinations can be present in Alzheimer's. https://www.alzheimers.org.uk/site/scripts/documents_info.php?documentID=1408 https://www.alzheimers.org.uk/site/scripts/documents_info.ph... > People with dementia are often thought to be hallucinating when in fact they are making a mistake about what they have seen (see 'Visuoperceptual mistakes' above). There are some specific forms of dementia, however, where hallucinations are more common. These include dementia with Lewy bodies and Parkinson's disease dementia. Hallucinations can also occur in Alzheimer's disease. > Hallucinations in people with dementia with Lewy bodies usually take the form of brightly coloured people or animals. They often last for several minutes and can occur on a daily basis. Around one in 10 people with dementia with Lewy bodies also experience smells that are not really there (known as olfactory hallucinations). People with dementia may also experience auditory hallucinations (hearing sounds or voices) and tactile hallucinations (sensing things that aren't there). This was the first Google result for [dementia hallucinations], although I guess my filter bubble has been heavily trained.

    Hallucinations are a common symptom of dementia, but not the type he described. The type he described are particularly common for another condition.

      This is what you said: > The spider-like hallucinations are classic alcohol-withdrawl symptoms not directly associated with dementia or alzheimer's. You said "not directly associated with alzheimer's". That's incorrect. Some, but not most, people with alzheimer's experience tactile hallucinations. Here's another cite: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3105559/ http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3105559/ > Alzheimer's disease > The prevalence rates of hallucinations in Alzheimer's disease (AD) range from 12 to 53%. Hallucinations in AD most often are visual, although auditory, tactile and olfactory hallucinations have also been observed. Hallucinations are most prevalent in the moderate to severe stages of the illness and do not seem to occur at the end stage of the disorder.

  These kind of hallucinations are not uncommon with NMDA receptor antagonists like DXM, might well be that receptor damage can cause similar symptoms.
