In humans, a variety of neurological and psychiatric conditions alter the tendency to use facial signals. One of the main symptoms of Parkinson disease (PD) is diminished facial expressivity or "masked facies," which refers to the expressionless appearance of individuals with the disorder.
Definition. A lack of facial expression often with staring eyes and a slightly open mouth. [
People with PD usually suffer from loss of facial expression on both sides of the face. Moreover, their eye movement is reduced, like wearing a mask. This symptom is usually called the “mask face” [13].

Visual: Hallucinations in people with PD are usually visual. Common hallucinations include seeing animals or people, such as a furry creature running by or a deceased loved one sitting in the room.
A person with Parkinson's disease may sometimes appear to have their "game-face on" they may look serious or depressed, or have a blank stare, sometimes hardly even blinking. If you've noticed any of these symptoms in yourself or a loved one, don't be alarmed.
Tremors, muscle stiffness and slowness of movement are all common early symptoms of Parkinson's – but there are also other signs to be aware of. Sleep and night-time problems are common in Parkinson's. People with Parkinson's are more likely to experience insomnia due to certain symptoms which can disrupt sleep.
Masking refers to hiding your authentic self in an effort to gain greater social acceptance. The costs of camouflaging your true personality and emotions can add up exponentially, causing you to experience a sense of loss, anxiety, and depression.

The reason for using face coverings
Although they may not prevent you from becoming infected with the virus, face coverings help prevent you from spreading it to others if you are unaware you are infected (some people don't have any symptoms, especially early in the infection).
Symptoms usually begin gradually and worsen over time. As the disease progresses, people may have difficulty walking and talking. They may also have mental and behavioral changes, sleep problems, depression, memory difficulties, and fatigue.
Some studies have reported that the average time from onset of Parkinson's to developing dementia is about 10 years. One large study found that about three-quarters of people who live with Parkinson's for more than 10 years will develop dementia.
Similar to slowness of movement (or bradykinesia), people with Parkinson's disease often report slower thinking and information processing (termed “bradyphrenia”). Attention and working memory, executive function, and visuospatial function are the most frequently affected cognitive domains in PD.
The study used a simple scratch and sniff test in which participants had to identify common odors such as cinnamon, lemon, gasoline, and onion. Results from the study showed that those who had a poor sense of smell were nearly five times more likely to develop Parkinson's than those with a good sense of smell.
When patients reach stage five – the final stage of Parkinson's disease – they will have severe posture issues in their back, neck, and hips. They will require a wheelchair and may be bedridden. In end-stage of Parkinson's disease, patients will also often experience non-motor symptoms.
It's possible for non-motor symptoms to start occurring up to a decade before any motor symptoms emerge. Years can pass before symptoms are obvious enough to make a person to go to the doctor.
Hallucinations and delusions usually happen in the later stages of Parkinson's. They can affect both younger and older people in the earlier stages of the condition, but this is less common.
Berries, green leafy vegetables, eggs, fish and oil have neuroprotective properties which can reduce cognitive decline and improve memory function. Yogurt, kefir and raw sauerkraut, natural probiotics, can also increase natural dopamine production.
Patients with Parkinson's disease (PD) can experience several behavioral symptoms, such as apathy, agitation, hypersexuality, stereotypic movements, pathological gambling, abuse of antiparkinsonian drugs, and REM sleep behavioral disorders.
Available studies have shown that compared with healthy controls, patients with PD are accompanied by high rates of premature death. This is usually caused by factors such as pneumonia and cerebrovascular and cardiovascular diseases.
However, some studies have identified cases where Parkinson's disease symptoms disappear. In one study, a 78-year-old man experienced a remission of all symptoms 16 years after his diagnosis. Although full remission is very rare, it can happen in some cases.
