- hyperactive: restless, agitation, hallucination
- mixed
What are the causes of delerium?
- change in environment and sensory impairment
- UTI
- constipation
- Hypoxia
- infection
- metabolic disturbance
- pain
- nurtrition
- lack of sleep
- hypothermia/pyrexia
- organ dysfunction
- environmental change
Investigation for delirium
- cognitive assessment: MMSE, AMTS
- confusion screen: FBC, UEs, LFTs, coagulation/INR, TFTs, calcium, B12, folate, glucose, blood cultures
- urinalysis
- consider imaging
What is the management of delerium?
- identify and treat the cause
- keep a consistent nursing and medical team
- ensure patient is as independent as possible and has required aids
- clock and orientation reminders, familiar objects, involve the family

- speech and motor deficit
- personality change
- behavioural and psychological disturbance
Investigation for alzheimers
- bedside cognitive
- FBC to rule out anaemia
- metabolic panel
- TSH to rule out thyroid
- B12
- CT/\MRI
Management of alzheimers
- supportive care: education, support, resources
- Occupational therapist: home safety evaluation
- Cholinesterase inhibitor: donepezil
presentation of lewy body dementia
- hallucination
- delusion
What is malnutrition?

- gait speed/timed up and go test
What are the causes of sarcopenia?
- nutritional
- inactivity
- disease: bone/joint, metabolic disorder, endocrine, cancer
- iatrogenic
How can you differentiate between sarcopenia and malnutrition?
- Sarcopenia: Decreased muscle mass and strength
- Malnutrition: decreased muscle mall with normal strength
What is the management of sarcopenia
- resistance exercise
What is the presentation of depression?
- depressed mood/loss of interest, most of the day, everyday for 2+ weeks
- diminished pleasure/interest in all/most activities everyday for 2+ weeks (anhedonia)
