Delirium
• Worsens prognosis- significant mortality
rate
• Lengthens stay in hospital- longer in bed,
falls, pneumonia
• Increased rates of institutionalisation
• Potentially treatable
• Up to 2/3 not detected
Delirium: Clinical Features
• Clouding of consciousness, attention,
memory, executive function all affected
• 2 types
• Apathetic
• Active, psychotic, behavioural symptoms
• Symptoms worse at night
Delirium:Risk Factors
•
•
•
•
•
•
•
•
•
•
•
Increasing age
Dementia
Sensory deficits
Previous episode
Severe comorbidity
Immobility
Sleep Disturbance
Alcohol Consumption
Operation
Dehdration
Low albumin
Delirium-Medication Risk factors
•
•
•
•
•
Benzodiazepines
Anticholinergics
Opiates
Digoxin
Warfarin
Delirium Causes
• Almost anything in combination with risk
factors
Delirium-Tips
• Sudden deterioration in mental state
consider delirium
• The greater the number of risk factors the
more delirium is likely
• Sometimes delirium can go on for weeks
Delirium:Treatment
• Identify and treat cause
• Modify risk factors
• Infections, metabolic, malignancy, cardiac,
vascular
• Consider hospital admission

Progressive
Impairment of cognition, personality and intellect
Orientation,

The Dementias: Behavioural and
Psychological Symptoms in
Dementia- BPSD
• Why are they important?
• Predict carer distress and breakdown of
supportive network
• Predict institutionalisation
• Nearly 90% of admissions to Larch
•
•
•

•
The Dementias: Behavioural and
Psychological Symptoms in
Dementia- BPSD
Mood
Anxiety as a presentation
Anxiety as a concomitant
Depression
Elation- often pre existing bipolar disorder

Psychological Symptoms in
Dementia- BPSD-Psychosis
• Hallucinations

The Dementias: Causes
•
•
•
•
•
•
•
•
•
Subdural
Brain tumour
Normal pressure hydrocephalus
Hypothyroidism
Low B12/folate

The Dementias: Causes
• Alzheimer’s Disease(AD) 50%
• Vascular Dementia(VaD) 10%
• Mixed Dementia-Alzheimer’s with
cerebrovascular disease AD/VaD 25%
• Dementia with Lewy Bodies(DLB) 10%
• Fronto Temporal Dementia (FTD) 2%
Alzheimer’s disease
•
•
•
•
•
•
Plaques, tangles
Insidious onset
Gradual decline
Memory orientation difficulties early on
Executive function impairment
Later on dyshasia, dyspraxia, agnosia
Vascular Dementia
• Pure form not that common
• Single large infarct
• Multi infarct dementia
• Subcortical dementia
RISK FACTORS
• Male
• Stroke/TIA
Alzheimer’s with Cerebrovascular
disease
Gradual deterioration
• RISK FACTORS
1. Family history dementia
2. Increasing age
3. Atrial fibrillation
4. Hypertension
5. Hypercholesterolaemia
6. Diabetes
7. Homocysteine
8. ?Lack of Exercise
Modifying Risk
• NB long latency(10+ years) between modifying
risk factor and seeing effect on disease
• ANTIOXIDANTS
• Vitamins C & E in combination
• ?Vitamin E delaying institutionalisation
• ANTIANFLAMMATORIES
• Non steroidal antiinflammatory agents ?Some
benefit if taken over many years
Modifying Risk
• Tobacco- risk not reduced-stimulation of nicotinic
receptors offset by other deleterious effects
• Alcohol- mild drinking up to 3 units of wine per day
benefit
• Statins- beneficial in TIAs, stroke, hypercholesterolaemia,
dementia-mixed results. May increase alpha secretase
• B12 & folate long term to reduce homocysteine?
• Oestrogen?
• Increased exercise?
• Mental stimulation?

PD and subcortical dementia
PD and AD
PD and hallucinations from treatment
Dementia with Lewy Bodies(DLB)
Dementia with Lewy Bodies

Neuroleptic sensitivity
Fronto Temporal Dementia
• 30% of younger onset dementia(45-65yrs)
• Duration 8yrs
1. Overactive-disinhibted, lack of
concern(orbitomedial frontal, anterior temporal)
2. Apathetic-perseveration, rigid thinking, lack of
volition(pan frontal)
3. Stereotyped ritualistic behaviour(striatum)
4. Semantic dementia-unable to understand
meaning of words, objects, sensations
5. Progressive non fluent dyshasia
Fronto Temporal Dementia
•
•
•
•
•
Liking for sweet things
Emotional blunting
Striking loss of insight
Ability may be enhanced-artistic or musical
Tip-frontal lobe symptoms often precede
memory problems
Other Dementias

• Creutzfeld-Jacob Disease-Classical-rapid
decline, myoclonus, abnormal EEG, death
in < 1 yr

Mild to moderate Alzheimer’s Disease

Diagnosis in specialist clinic
Treatment initiated by specialist but may be continued by
primary care under shared care protocol
• Seek carers’ views
• Assess 2-4/12 after maintenance dose. Continue only if
improvement in MMSE score or no deterioration and
behavioural or functional improvement
• Review every 6/12- MMSE must remain >12 and
worthwhile effect on global functional and behavioural
condition
Goals of Treatment
•
•
•
•
•
Enhance Cognition
Increase autonomy
Decrease behavioural symptoms
Slow or arrest progression of the disease
Primary prevention in the presymptomatic
stage

Stopping CHEIs
MMSE <12
Marked deterioration
Withdraw over 2/52
Often severe relapse- need to restart within
4/52
The Dementias:CHEIs
• Side effects-cholinergic-nausea,
headache,sweating, bradycardia dizziness
• Cautions-asthma, sick sinus syndrome
• Outcome-actual improvement in behaviour
cognition, function, psychosis
• Slowing of deterioration
• Up to 18/12
• Stopping
The Dementias: Treatment
Memantine
• Licensed for moderate to severe dementia
• Not supported by Priorities Committee in W
Berks
• Modest evidence of benefit in cognition,
ADL, behaviour
Other Treatments
• NSAIDs-Low rates of AD in patients with
RA. Insufficient evidence
• HRT- no effect in established disease,
possibly preventative
Other Treatments: Antioxidants
• Vitamin E ? Delays institutionalisation.
Dose 1000 IU/day

Depressive Disorders- Treatment
• Prevention of Relapse and Recurrence
• Continue medication during recovery
• Stay on medication for at least 1 yr after
recovery
• Maintenance treatment
Depressive Disorders- Treatment
• Antidepressants- NNT of 4
• SSRI-under 80yrs, avoid if patient taking aspirin
NSAIDs, history of peptic ulcer
• Over 80s-mirtazapine( sedation), venlafaxine
(hypo or hypertension, cardiac disease),
lofepramine
• Moclobamide=MAOI B reversible
• Phenelzine
• All –low sodium-inappropriate ADH secretion
• Discontinuation reactions- possible after 8 weeks

Resistance
• Substitute with another antidepressant (fewer
interactions, easier to attribute success or failure or
side effects)
• Augmentation-( do not need to withdraw, possible
synergy)
• TCA with SSRI
• SSRI+Mirtazapine
• Antidepressant + Lithium
• Up to 300mgs of venlafaxine

• Single episode major depression-1 yr after
recovery
• > 3episodes continue indefinitely at
therapeutic dose
• TCA, citalopram
• Antidepressant+ psychological Rx
Depressive Disorders- Prognosis
• Thirds- 1/3 got better, 1.3 had relapses, 1/3
continuing sympotms
• Better than this with active interventionOAP-2/3 got better
• Psychotic depression lethal- excess
mortality from physical conditions
• Increased risk of heart attacks and stroke
• Vascular depression poor prognosis
