Difference between mental health act and mental capacity act
MHA is only about compulsory treatment of mental disorder, for the benefit of the patient but also,
at times, for the protection of others.
MCA is about empowering people to make decisions for themselves, as much as possible and,
where they can’t, determining what is in their best interests. It applies to almost all kinds of decision,
with very few exceptions, one of which is the treatment covered by the MHA.
Where a patient is detained under the MHA for treatment of the mental disorder, the MCA will
continue to apply for all other kinds of decisions. The patient may still have capacity to make decisions
about medical treatment for physical health, for example, and if they do have that capacity they are
perfectly entitled to refuse medical treatment for a gangrenous leg, for example, despite being
detained for compulsory treatment of their mental health.
Presentation of dementia
Cognitive impairment (memory loss, language, attention, thinking, orientation, problem solving)
Psychiatric or behavioural distrubances
Difficulties with activities of daily living
Presentation of Alzheimers disease
progressive and global cognitive impairment memory loss word finding difficulty apraxia difficulty planning disorientation apathy altered eating habits incontinence insidious onset No disturbance in consciousness
Pathophysiology of alzheimers
degeneration of cerebral cortex with cortical atrophy
Accumulation of beta amyloid plaques and neurofibrillary tangles
Pharmacological management of alzheimers
Acetylcholinesterase inhibitors eg donepezil, rivastigamine, galantamine (cholinergic side effects)
Memantine is second line
Presentation of vascular treatment
sudden onset and stepwise treatment
Evidence of vascular pathology
Tx contol vascular risk factors, lifestyle changes
Investigations of suspected dementia
Abbreviated mental test/ MMSE/ 6 CIT CT/MRI- vascular damage? FBC, ESR, U+E- rule out infection B12, folate Investigate substance misuse Hx of head trauma
Presentation of delirium
DELERIUM
Disordered thinking Euphoric/ fearful/ depressed/ Language impaired Illusion/ delusions/ hallucinations/ Reversal of sleep wake cycle Inattention Unaware/ disorientated Memory deficits
Causes of delirium
acute/ systemic infections intracranial infections drugs- opiates, sedatives, levodopa, anticonvulsants alcohol withdrawal Metabolic distrubances Hypoxia Stroke/ MI head injury epilepsy nutritional deficiencies post surgery
Investigations of delirium
FBC- anaemia/ infection U+Es- metabolic disturbances Urinanalysis chest x ray ECG ABG Dug levels- digoxin, lithium, alcohol Blood glucose Neurological imagine
Septic screen
Blood culture CXR skin and throat swabs urine microscopy and cultures lumber puncture
stress incontinence vs functional incontinence vs urge incontinence vs overflow incontinence
Functional
-unable to get to to toilet in time due to poor mobility/ unfamiliar surroundings
Stress
- leakage due to incompetent sphincter
- when coughing/ laughing/ on exertion
- 50% of post menopausal women
- pelvic floor weakness- eg uterine prolapse, urethrocele
Urge= overactive bladder
- urge to urinate quickly followed by uncontrollable emptying of bladder
- detrusor muscle instability or hyperreflexia
overflow
- chronic bladdeer outflow obstruction
- most likely cause in men- prostate enlargement
Management of overflow incontinence
Lifestyle: avoid caffeine, alcohol, void twice in a row to aid emptying, bladder training
alpha-blockers: tamulosin (decreases smooth muscle tone)
5 alpha reductase inhibitors eg finastende
Surgery- TURP- transurethral resection of prostate
Management of Urge incontinence
Bladder training
Pelvic floor exercises
Antimuscarinic=anticholinergic- tolderidine and oxybutinin]
topic oestrogen if post menopausal urgency
Botox
mirabegron- B3 adrenergic antagonist
