Delirium and mental status Flashcards
Aspects of Appearance
Physical appearance (hygiene)
Behavior (mannerisms and psychomotor retardation)
Attitude (cooperative? guarded?)
Aspects of Behavior
Behavior (mannerisms and psychomotor retardation)
Mood vs Affect?
Mood is the experienced emotion that the patient expresses
Affect is the emotion that the clinician observes the patient to express.
Thought process vs Thought Content
Thought process is how the patient forms thinking. Whether patient’s thoughts are logical, goal directed etc. Pushed speech?Tangential? Loosening of Association? Word salad?
Thought Content is the types of ideas expressed. Delusions? Suicidal/homicidal thoughts phobias, compulsions, hallucinations, Illusions
Hallucination vs illusion
Hallucinations are when a person senses/sees/hears something without external stimuli
Illusions are when there is a stimuli but there is an inappropriate interpretation (everyone’s face in an audience turning into the devil)
questions to assess sensory and cognition perception
Memory: recent, recent past, remote
fund of knowledge
Attention: spell world backwards, subtract 7 from 100 a bunch
Reading: read simple sentences
Abstract: similarities between objects, meaning of proverbs
Insight vs judgement vs reality testing
Insight is the patient’s awareness and understanding of dx. This could include denial or blaming dx on something else
judgement is ability to understand the outcome of his or her actions “what would you do if you smelled smoke in a crowded theater”
Attention, behavior, cognition associated with delirium
ACUTE ONSET, VARIABLE THROuGHOUT THE DAY
Reduced clarity of awareness
reduced ability to focus, sustain or shift focus
change in cognition (memory deficity, disorientation language disturbance)
Development of perceptual disturbance
Psychosis vs Delirium vs dementia
Delirium is not necessarily an organic process but results from anoxia which cause excess dopamine production, stimulates NT release as well as reduces reuptake of NTs from synapses so synaptic cleft is flooded with Dopamine
Major causes of delirium
Intracranial disturbances (epilepsy, neoplasm in the temporal lobe)
Extracranial drugs (anticholinergics, anticonvulsants, steroids, opiates, sedatives, antihtns)
Posions (CO2, heavy metals)
Endocrine dysfunction
Organ disease (liver, kidney, CV, lung)
Thiamine, B12, folic acid deficiency
Systemic infection
Electrolyte imbalance
**Postoperative over 60yo especially **
Medical disorders in delirium
Epiliepsy,
Haloperidol is the pharmacological choice for delirium because?
It is a pure dopamine antagonist (it doesn’t have as many receptors on it, just binds dopamine as compared to risperidone which has more receptors )
Also is can be administered in many different ways.
