Why Parkinson's Patients Often Have Their Mouth Open: Exploring Facial Changes
Parkinson's disease progressively impacts movement and motor control in those affected. While well-known for causing tremors, Parkinson's also commonly affects facial muscles in ways that may leave patients with their mouth open persistently.
Understanding Parkinson's Impact on Facial Muscles
Parkinson's disease stems from a loss of dopamine producing neurons deep in the basal ganglia region of the brain. Dopamine helps transmit signals facilitating controlled body movements. As dopamine production wanes, patients lose normal muscular control.
In the early stages, Parkinson's characteristic tremors and rigidity mostly impact limb mobility. However, as Parkinson’s advances, dopamine deficiency increasingly affects the face too.
Facial Changes Associated With Parkinson's
Common Parkinson’s related facial alterations include:
Hypomimia: Reduced facial expressions due to rigid facial muscles
Mask-like expressions: Fixed, stared facial appearance lacking emotions
Loss of eye blinking: Eyes remain wide open
Mouth changes: Lips often parted, sometimes with drooling
Why Parkinson's Patients Often Have Their Mouth Open
The loss of natural facial movement control in Parkinson’s frequently leaves patients unable to fully close their lips. Reasons this "open mouth posture" occurs include:
Oral rigidity - Stiff lip, tongue, and jaw muscles resist moving to a closed position.
Saliva control issues - Excess saliva drips uncontrollably from an open mouth.
Breathing problems - Open mouth allows easier air intake if nasal breathing affected.
Dental pain - Tooth loss or denture issues may make closing lips difficult or uncomfortable.
Managing Open Mouth Issues in Parkinson’s Patients
While an open mouth alone rarely causes medical concerns, it can impact speech clarity, promote drooling, and detract from appearance. Implementing management strategies improves quality of life.
Oral Motor Exercises
Physical and speech therapists often recommend facial muscle exercises promoting mobility. This strengthens muscles resisting Parkinson’s rigidity. Examples include:
Puckering and smooching lips
Raising and lowering eyebrows
Scrunching and relaxing nose
"Cheesy smile" stretching mouth motions
Perform exercises daily with assistance. Over time, greater facial dexterity enables better voluntary mouth closure.
Medications Improving Motor Control
Doctors may adjust Parkinson's medications to reduce muscular rigidity. Providing smoother dopamine activity relaxes tense facial muscles. Specific drug options include:
Levodopa - Primary Parkinson's medication, dopamine precursor
Dopamine agonists - Mimic dopamine effects
COMT inhibitors - Lengthen levodopa efficacy
Anticholinergics - Balance neurotransmitter levels
Note side effects or worsening movement problems may occur. Work closely with doctors determining suitable regimens.
Botox Injections
Botox injections temporarily paralyze facial muscles. Weakening overactive muscles improves motility in others. Benefits typically persist about 3 months before re-injection needed. Researchers still debate botox long term impacts for Parkinson's.
Speech and Swallowing Assistance
Speech-language pathologists guide Parkinson’s patients on proper tongue placement, chewing motions, and head positioning aiding mouth closure for clear speech and easier eating. Advice may include:
Keep teeth slightly apart, tongue on roof of mouth while talking
Tuck chin slightly or tilt head for gravity assist swallowing
Eat slowly, take smaller bites mixed with liquids
Additionally, address dental issues like ill-fitting dentures causing discomfort closing mouth.
Coping With Facial Expression Changes
For some, Parkinson's lack of facial affect heavily impacts self-image and communication. Support groups connect patients facing similar struggles. Tips helping overcome appearance related concerns include:
Meeting peoples' eyes when talking to show engagement
Sit facing listeners for better speech comprehension
Use hands to gesture emotions
Explain you have Parkinson's if needed
While Parkinson’s effects on facial musculature can’t be eliminated, implementingmanagement techniques provides relief allowing patients to remain active despite disease progression.
FAQs
Why do Parkinson's patients often have their mouth open?
Facial muscle rigidity, saliva control problems, nasal breathing issues, and dental pain can all cause Parkinson’s patients difficulty fully closing their mouths.
Does an open mouth impact Parkinson's patients?
An open mouth can affect speech clarity, contribute to excess drooling, and undermine self-confidence but generally doesn't cause serious medical problems.
What treatments help close the mouth in Parkinson's?
Facial muscle exercises, adjusted Parkinson’s medications, botox, speech therapy techniques, addressing dental issues, and simple posture changes can all enable mouth closure.
Why do Parkinson’s patients have limited facial expressions?
Dopamine loss rigidifies facial musculature leading to fixed, mask-like expressions. Patients lose ability to convey emotions through natural facial movements.
How do you cope with Parkinson’s facial appearance changes?
Support groups, conveying engagement through eye contact, gesturing, strategic positioning facing listeners, and explaining medical conditions can overcome facial expression barriers.
