- Activated charcoal 50g if within 1 hour of presenting
* Specific antidotes and measures
Management of DSH or suicide attempt - psychiatric assessments?
o Psychiatric Assessment by PLN once medically optimised
• Risk assessment in A&E or on ward prior to discharge
• Refer to psychiatry if psychiatric disorder or high-risk

Definition of Alzheimer’s Disease?
- Primary degenerative cerebral disease of unknown aetiology which results in prominent cognitive and behavioural impairment
- Beta-amyloid precursor protein (APP) accumulates in brain parenchyma to form typical lesions

o Beta-amyloid deposition
o Senile plaques
o Neuro-fibrillary tangles (Tau proteins)
o Acetyl-choline levels reduced
Symptoms of Alzheimer’s Disease?
Insidious onset, progressive decline
Early symptoms
o Forgetfulness, deterioration of self-care, changes in behaviour
5 A’s of Alzheimer’s
o Amnesia (recent events)
o Aphasia (difficulty with speech)

Assessment of Alzheimer’s Disease?
- Mental State Examination
- Cognitive Testing – AMTS, MMSE, ACE-3
- Physical Examination
Investigations of Alzheimer’s Disease?
- Blood tests
o FBC, ESR, U&Es, creatinine, HbA1c, LFTs, TFTs, B12 and folate - EEG – exclude delirium, CJD
- Brain imaging – CT/MRI
Management of Alzheimer’s Disease - general principles?
o Brain activities such as regular activities, word games, socialisation
o Inform DVLA
o Treat modifiable risk factors
o Manage carers, financial support, legal (lasting powers of attorney)
Management of Alzheimer’s Disease - non-pharmacological?
o Group cognitive stimulation programme
o Memory enhancement strategies (Reminder notes, lists, reorganisation of possessions)

Management of Alzheimer’s Disease - pharmacological?
If mild-to-moderate AD:
o AChEIs monotherapy
• 2nd generation – donepezil, rivastigmine, galantamine (longer half-life and commonly used)
In moderate-to-severe AD - add on:
o NMDA-receptor partial antagonists
• Protects from glutamate excitotoxicity
• Memantine
Management of Alzheimer’s Disease - follow up?
o Assessment every 6 months to see if drug effective and should only be continued if having benefit on cognition, global, functional
