McHugh and Slavney

Dementia is now ‘Neurocognitive Disorder’(NCD)Further Defined as ‘Major’ or ‘Minor’

What’s in a name?

Greater phenomenological correctness – especially with the growing base of literature defining specific aetiologies

Broader term - can include syndromes with only one cognitive domain affected (e.g. ‘amnestic d/o’)

NCD is often the preferred term in the literature and in practice – such as in younger individuals or those with TBI

Dementia is ok to still use if it helps communicate the nature of the illness

Neurocognitive DisorderMajor

Concern of the individual, informant or clinician

‘significant’ cognitive decline – needs IADL assistance

Not due to delirium or another mental disorder

Minor

Concern of the individual, informant or clinician

‘modest’ cognitive decline – preserved IADLs but needs compensatory strategies or accommodation

Not due to delirium or another mental disorder

FDA Approved Treatments for Complications of AD

Behavioral Management

Environmental vs. Medicationmeds are a last resort

The “4D Approach”adapted from Practical Dementia Careby Rabins, Lyketsos, and Steele

Our Assumptions:

Behavioral dyscontrol can have multiple etiologies.

They can be distinguished from each other.

Identifying the cause can directly lead to treatment strategies.

There is rarely “one-best” approach to address these issues.

Directed “trial and error” is the rule, not the exception.

The “4D Approach”

Define and Describe

Decode

Devise a treatment plan

Determine “does it work?”

Behavioral Management

Environmental vs. Medicationmeds are a last resort

If you chose a medication… Which One? antipsychotics

typical vs. atypical

benzodiazepine

othere.g valproate

CATIE-ADLon S. Schneider et. Al.

Primary outcome – time to discontinuation for any reasongreat “real world” approach to study design

Atypicals were no better “tolerated”

Big media spin after data released:Known higher mortality per FDA.Now evidence of “lack of efficacy.”Therefore, doctors are abusing elderly patients.

Actually, study shows:Placebo stopped more due the lack of benefit than S.E.Atypicals stopped more due to S.E. than lack of benefit.

What you (and your patients) should watch for:

EPS

Dystonia

Akathisia

NMS

TD

Glucose Dyscontrol

Cholesterol Dyscontrol

Delirium

Torsades de pointes

Postural hypotension

Weight gain

Agranulocytosis

Increased risk of all cause death

What About Anticonvulsants?

Initial trials were promising, but…

Most recent studies show far less benefit if not more behavioral discontrol

However, can be helpful in some augmenting strategies or in catastrophic reactions.

What NOT To Use

Benzodiazepine Side Effects

Sedation

Lets Define the Atypicals

Atypical: “Deviating from what is usual or common or to be expected” – Websters

So, what are Typical Antipsychotics?Drugs that had high probability of inducing Extrapyramidal Side Effects (EPS)

EPS ≡ Parkinsonismvia high D2 antagonism

High Potency vs. Low PotencyEPS generally mitigated by anticholinergic activityexception is risperidone which uses 5HT2 antagonism

Examples: high: haloperidol, fluphenazine, droperidol, pimozidelow: chlorpromazine, thioridazine,

Lets Define the Atypicals – not a class created of equals

Clozapine (Clazaril)

Risperidone (Risperdal)

Olanzapine (Zyprexa)

Quetiapine (Seroquel)

Ziprasidone (Geodon)

Aripiprazole (Abilify)

Paliperidone (Invega)

Asenapine (Saphris)

Iloperidone (Fanapt)

Lurasidone (Latuda)

Clinical Recepterology

Receptor we antagonize: What we watch for:

D2 EPS, (+) symptom relief, hyperprolactinemia

5-HT2a (-) symptom relief, mitigates EPS

5-HT2c Antidepression

α1 Postural hypotension

H1 Weight gain, sedation

M1 Weight gain, sedation, urinary retention, confusion, constipation, dry mouth etc…
