Dr.Mansour K. Alzahrani

Objectives:

Define the dementia

Discuss the prevalence of dementia

Discuss the impact of dementia on the individual and the family

Evaluate the patient with suspecting dementia

Discuss the diagnostic criteria of dementia

Explain the common types of dementia

Discuss the pharmacological and non-pharmacological management of dementia

Define the dementia

Dementia is chronic deterioration of cognitive function characterized by multiple cognitive deficits and deterioration of global intellectual ability.

Chronic deterioration of cognitive function

The dysfunction involves memory, behavior, personality, judgment, attention, language, abstract thought, and other executive functions

The deficits seen in dementia interfere with the person's occupational and social functioning

Memory impairment is generally a prominent early symptom

Discuss the prevalence of dementia

AS MANY AS 26 MILLION PEOPLE AROUND THE

WORLD ARE LIVING WITH ALZHEIMER’S DISEASE.

THE SIXTH-LEADING CAUSE OF DEATH IN THE

WORLD.

More than 50,000 pts in K.S.A.

Impact on the individual and the family

Patient Family

Evaluate a patient with suspecting dementia

Initial Manifestations

Impaired recent memory (repeats self, forgets what was heard or read, misplaces things)

Poor decision making, judgment, or problem solving; decreased organizational skills

Difficulty learning new tasks or performing routine tasks

Problems managing money (balancing checkbook, forgetting to pay bills)

Difficulties expressing self (word finding) or participating in conversation

Getting lost in familiar areas, forgetting known routes while driving

Change in personality (apathetic, disinhibited), mood

(sad, irritable), or behavior (odd or bizarre)

Temporal Factors

Mode of onset (acute, subacute, insidious)

Course (static progressive, improvement over time, fluctuating)

Individual Factors

Cultural background

Educational level

Social/occupational demands (and changes incurred by symptoms)

Life circumstances (social, financial, occupational, living arrangements)

Hereditary Factors

Familial risk factors (stroke, hypertension, diabetes mellitus)

Genetic: family history suggesting autosomal dominant inheritance or multiple cases in family suggesting non–mutation-associated familial disease

(e.g., apolipoprotein E4–associated Alzheimer disease)

Medical/Neurological Conditions

General medical conditions (hypothyroidism, hypertension, diabetes mellitus, heart disease)

Neurological conditions (transient ischemic attacks, strokes, seizures, syncope, head trauma)

Associated motor features (tremor, gait difficulties, speech/swallowing disturbance, ataxia)

Sleep disturbances (sleep apnea, insomnia, sleepassociated movement disorder)

Examination:

Ex: mini-mental examination to test the cognitive functions.

Neurological examination

General medical examination

Diagnostic criteria of dementia

DSM-IV Criteria for Dementia:

 ▪ The development of multiple cognitive deficits that include memory impairment and at least one of the following:

 ▪ Aphasia

 ▪ Apraxia

 ▪ Agnosia

 ▪ Disturbance in executive functioning

 ▪ The cognitive deficits must meet the following criteria:

 ▪ Be sufficiently severe to cause impairment in occupational or social functioning

 ▪ Represent a decline from a previous higher level of functioning

Common types of dementia

Management of dementia

Management goals in early dementia center on improving or stabilizing cognitive ability and mood, maintaining or reestablishing independence, promoting autonomy, and effective planning for the future.

Potential interventions in management of dementia.

non-pharmacological management

Stimulation-oriented approaches (e.g., recreational activities or therapies, music therapy, dance therapy, art therapy, exercise, multisensory stimulation, simulated presence, aromatherapy)

Emotion-oriented approaches (e.g., supportive psychotherapy)

Cognition-oriented approaches (skills training)

Treatments for cognitive and functional losses

Cholinesterase inhibitors: donepezil (sever), rivastigmine, galantamine(mild-modrate)

Memantine (modrate – severe )

Vit. E ( no more)

NSAIDs, statin and estrogen ( not recommended)
