Q

Dementia with Lewy Bodies

A
  • Lewy Bodies – alpha synuclein and ubiquitin positive inclusions
  • In Parkinson’s Lewy Bodies are confined to the substantia nigra, in DLB they are more widespread and also involve cortical regions
  • Often thought of hybrid of PD and AD
  • Visual hallucinations
  • REM behavioural sleep disorder
  • Autonomic dysfunction (postural hypotension) - Neuroleptic sensitivity
    MRI – similar to AD
    SPECT – may show disproportionately severe occipital hypoperfusion
    DatSCAN – to differentiate AD from PD (shows reduction in dopamine transportation in PD)

58
Q

What are the 6 ICD-10 diagnostic criteria for dependence syndrome?

A
  1. string desire or sense of compulsion to take the substance
  2. difficulties in controlling substance taking behaviour: onset, termination, levels of use
  3. Physiological withdrawal state when substance use has been ceased or reduced
  4. evidence of tolerance, such as increased doses of the psychoactive substance are required in order to achieve effects originally produced by low doses
  5. progressive neglect of alternative pleasures or interests because of psychoactive substance use increased amount of time necessary to obtain or take the substance or to recover from its effects
  6. persisting with substance use despite clear evidence of overly harmful consequences, such as harm to the liver through excessive drinking, depressive m mood states consequent to periods of heavy substance use, or drug-related impairment of cognitive functioning

you need 3 or 4 of these 6 to diagnose the dependence
