What is Facial Masking?
Facial masking (hypomimia) also referred to as a "flat affect", is a common Parkinson's symptom where people experience:
Reduced facial expressions
Less frequent blinking
Diminished reactive facial expressions like smiling or frowning
Appearing less animated during conversations
Important: This change in facial expression does not accurately reflect the person’s emotional state. It also does not mean the person’s personality or interests have changed. Just like walking and limb movement can be slowed/impacted, so too can facial movement!
Why It Matters
Facial expressions are crucial for communication and relationships. When they're reduced, others may misinterpret this as:
Disinterest or boredom
Sadness or depression
Anger or frustration
This can strain relationships and lead to social isolation for people with PD, even though the person's internal emotions haven't changed.
Treatment Options
Medication: Parkinson's medications that help with movement may also improve facial expressions.
Speech Therapy: Specialised therapists can provide crucial tips for improving communication strategies and may even prescribe relevant facial and voice exercises.
Family Education: Help loved ones understand that reduced expression doesn't mean reduced interest or emotion! Discussing this openly with your friends, family or support network to increase understanding and reduce potential strain.
When to Seek Help
Contact your healthcare provider if:
You notice significant changes in facial expressiveness
Family comments on reduced expressions
Social interactions become challenging
Key Takeaway
Reduced facial expression does not equal reduced emotion or interest!
Understanding this symptom helps maintain relationships and quality of life for everyone involved.
