Therapeutic Communication with People Who Have Cognitive Impairment (Dementia)

Dementia and Cognitive Impairment

Overview of Ageing and Dementia

Dementia is a progressive deterioration in cognitive function, commonly associated with ageing. It is a major health concern, especially in permanent residential aged care, where a significant proportion of residents are affected.

• Dementia: A chronic syndrome characterized by a decline in memory, thinking, behavior, and the ability to perform everyday activities.

• Prevalence: Most people in permanent residential aged care have dementia.

• Types of Dementia:

  • Alzheimer's Disease: Accounts for approximately 70% of all dementia diagnoses.

  • Vascular Dementia: Shares risk factors with cardiovascular disease (e.g., hypertension, diabetes).

  • Lewy Body Dementia: Presents with symptoms similar to Parkinson's Disease, such as movement difficulties and visual hallucinations.

  • Young-Onset Dementia: Occurs in younger individuals, often under 65 years of age.

Symptoms and Progression of Dementia

Early Symptoms

Dementia often has a gradual onset, making early symptoms easy to overlook. The presentation can vary significantly between individuals.

• Memory loss (especially for recent events)

• Difficulties with everyday tasks

• Confusion in familiar environments

• Difficulty with words and numbers

• Problems with problem-solving

"If you have seen one person with dementia, you have seen one person with dementia." This highlights the individual variability in symptoms and progression.

Progression of Symptoms

• Increasing memory loss (forgetting names, recent events)

• Becoming confused at home

• Communication difficulties (finding words, following conversations)

• Problems with personal care (dressing, bathing)

• Behavioral changes (wandering, repeated questioning)

Advanced Dementia

• Near total dependence and inactivity

• Severe disturbances (awareness, recognition, self-care)

• Unawareness of time and place

• Difficulty recognizing familiar people

• Assisted self-care required

• Escalating behavioral changes

Delirium vs. Dementia

Key Differences

• Dementia: Chronic, progressive, irreversible decline in cognitive function.

• Delirium: Acute, reversible clinical condition characterized by sudden changes in mental status, fluctuating levels of consciousness, and impaired attention.

Delirium can be fatal in older adults and often requires prompt identification and management.

Principles of Therapeutic Communication

Communication Model

Effective communication involves a sender, a message, a channel, and a receiver, with feedback completing the process. In dementia care, both receptive (understanding) and expressive (speaking) communication may be impaired.

• Sender: Initiates the message

• Receiver: Interprets the message

• Channel: The medium (verbal, non-verbal, written)

• Feedback: Response from the receiver

Barriers in Dementia

• Encoding difficulties: Trouble expressing thoughts

• Decoding difficulties: Trouble understanding messages

Person-Centred Communication

Core Principles

Person-centred care emphasizes the individuality and personhood of people with dementia. Communication should support their autonomy, dignity, and emotional well-being.

• Maintain awareness of interpersonal interactions

• Support expression of personal values

• Conversation as caring: Every interaction is an opportunity to provide care and validation

"They may forget what you said, forget what you did, but they will never forget how you made them feel." – Maya Angelou

Communication Strategies for Cognitive Impairment

General Strategies

• Gain attention before speaking

• Use clear speech and body language

• Keep messages simple

• Allow time for response

• Use visual aids (pictures, gestures)

• Repeat and rephrase as needed

• Engage in meaningful conversation

Validation and Reminiscence

• Validation Therapy: Accepting the person's reality and feelings, rather than correcting them.

• Reminiscence Therapy: Encouraging discussion of past events, which can provide pleasure and support emotional well-being.

Stages and Symptoms of Dementia: Summary Table

Stage	Key Symptoms
Early	Memory loss, difficulty with tasks, confusion in familiar places, word-finding problems
Middle	Increasing memory loss, confusion at home, communication difficulties, problems with personal care, behavioral changes
Late	Near total dependence, unawareness of time/place, inability to recognize people, severe self-care deficits, escalating behavioral changes

Summary

• Dementia is a progressive, chronic condition affecting cognitive function, with Alzheimer's disease being the most common type.

• Symptoms progress from mild memory loss to severe dependence and behavioral changes.

• Therapeutic communication and person-centred care are essential for supporting people with dementia.

• Effective strategies include clear, simple communication, validation, and reminiscence therapy.
