Study Notes
Neurocognitive Disorders
- Neurocognitive disorders is a new global term encompassing both delirium and dementia diagnoses (DSM-5, 2013). Previously, these were called organic mental syndrome and disorder.
Causes
- Cognitive psychotic conditions have diverse causes (etiologies).
- A mnemonic "MEND A MIND" helps remember causes of cognitive impairment:
- M - Metabolic disorder
- E - Electrical disorder
- N - Neoplastic disease
- D - Degeneration
- A - Arterial disease
- M - Mechanical disease
- I - Infectious disease
- N - Nutritional disease
- D - Drug toxicity
Delirium
-
Definition: An acute organic mental syndrome characterized by a clouding of consciousness, accompanied by disorientation, memory problems, and reduced concentration. It is reversible.
-
Prevalence: Up to 15% of patients over 65 are delirious upon hospital admission.
-
Risk factors: Increasing age, underlying dementia, and physical illness.
-
Outcome: Full recovery is usual but there is significant associated morbidity and mortality.
-
Onset: Sudden and tends to resolve rapidly with cause identified and appropriate treatment. Common in children and those aged 60 and above.
-
Types:
- Delirium due to a general medical condition
- Substance-induced delirium
- Substance intoxication delirium
- Substance withdrawal delirium
- Delirium due to multiple etiologies/delirium not otherwise specified
-
Causes (categorized):
- A. Infections: Systematic infections (e.g., malaria, typhoid fever, pneumonia), etc.
- B. Drug intoxication/withdrawal: Alcohol, anxiolytics, opioids, CNS stimulants, cocaine, crack, amphetamines, marijuana, etc.
- C. Neurological disorders: Seizures, head trauma
- D. Postoperative state; puerperium (post-partum); hypertensive encephalopathy
-
- Drugs: Antibiotics, antiparkinsonian, anticholinergics (and anti-tuberculosis), anticonvulsants, analgesics, anti-inflammatory
-
- Metals and gases: Mercury, Lead, Arsenic, Carbon Monoxide
Clinical Features of Delirium
- Altered state of alertness, awareness, and consciousness (may fluctuate between hyperalert and obtunded; lucid intervals may occur).
- Onset may be dramatic/sudden but can be difficult to detect and may evolve over days/weeks.
- Disorientation and confusion. Decreased attention, concentration, and memory.
- Psychotic symptoms: Paranoia, hallucinations (often visual).
- Behavioral disinhibition; emotional liability; irritability.
- Psychomotor retardation or agitation (may vary in a 24-hour period)
- Fragmented sleep/wake cycle; increased agitation at night.
- Usually reversible with correction of the underlying etiology.
Investigations
- Aim for minimal but thorough investigations: Blood HB, Blood Urea, Electrolytes, urinary sugar and protein, Bender Gestalt Test, Memory Test, Fundus Examination, X-ray of skull, EEG, CSF Routine, Brain Scan, Brain Biopsy
Dementia
- Definition: Characterized by a (usually) insidious but sometimes acute development of generalized brain dysfunction with multiple cognitive deficits resulting in impairment of social and/or occupational functioning and decline from previous levels.
- Consciousness: In contrast to delirium, awareness and mental alertness are intact and stable in the early phases of dementia.
- Memory impairment: The hallmark of dementia—loss of recent and past memories, as well as difficulty learning new information.

- Treatment strategies for withdrawal and dependence.
Alcoholism
- Excessive and prolonged alcohol intake, leading to physical and mental illness, impacting socio-economic functions and relationships.
- Causes: Stress, peer influence, poor upbringing, anxiety, hereditary factors, low self-esteem, occupations (e.g. breweries, bartenders, mortuary workers) and curiosity
- Effects on CNS: Depression (impairing memory, reasoning). Large doses lead to e.g.: muscular in-coordination, poor judgment, nausea, vomiting, diplopia, ataxia, amnesia, cold, clammy skin. May led to coma and death.
- Possible alcohol-related psychoses: pathological intoxication (state of acute excitement with violence and loss of self-control). Dipsia mania (periodic excessive drinking bouts, followed by abstinence periods; causes neglect of work and personal hygiene)
- Symptoms of Delirium Tremens (alcohol withdrawal delirium).
- Causes of Delirium Tremens (e.g., sudden withdrawal, reduction in alcohol consumption, pre-existing physical issues).
- Management of alcoholism including hospitalization, close observation, complete bedrest, administration of anxiolytics or sedatives; nutritional support (vitamins and fluids) and personal hygiene attention.
Other Cognitive Impairments
- Briefly describe some other impairments (e.g., Amnestic syndrome; Organic Delusional Syndrome; Organic Hallucinations; Organic Mood Syndrome; and Organic Anxiety Syndrome & Organic Personality Syndrome) as separate disorders with related psychological/behavioral effects and treatment strategies.
Prevention of Drug/Alcohol Dependence
- Education on the harmful effects of drug/alcohol abuse targeting particularly youth and other educational initiatives/programs.
- Legal interventions include banning certain drugs and requiring prescription, as well as proper distribution and sale strategies.
