Secondary Motor Symptoms of Parkinson’s Disease
Parkinson’s disease is characterized by a range of motor symptoms, including secondary motor symptoms that can significantly impact an individual’s daily life. These symptoms often emerge as the disease progresses and can vary from person to person.
One of the secondary motor symptoms of Parkinson’s is speech difficulties. Individuals may experience changes in their ability to speak clearly and coherently. This can manifest as slurred speech, a softer voice, or difficulties with pronunciation.
Another common secondary motor symptom is a stooped posture. Parkinson’s can cause individuals to develop a hunched or bent-over posture, which can affect their balance and overall mobility.
Restless, fidgety movements called akathisia can also be observed in individuals with Parkinson’s. It is important to note that akathisia can also be a side effect of certain medications used to treat the disease. These movements can be involuntary and may cause discomfort or restlessness in affected individuals.
Physicians will also evaluate reported symptoms such as unwanted accelerations in movement or speech. Some individuals may experience sudden, uncontrollable bursts of movement or rapid speech. These symptoms can significantly impact daily activities and social interactions.
Many people with Parkinson’s disease begin to experience difficulty with precise hand movements, such as working a computer mouse or sewing. This can be attributed to bradykinesia, a slowness of movement commonly associated with Parkinson’s. One specific manifestation of bradykinesia is micrographia, a change in a person’s handwriting. As the disease progresses, an individual’s handwriting may become much smaller and the words may crowd together.
It is important to note that while micrographia can be an early symptom of Parkinson’s, it is not present in every person with the disease. The presence and severity of secondary motor symptoms can vary from individual to individual.
Dysphagia and its Link to Parkinson’s Disease
Recent studies have debunked the previous notion that swallowing problems, known as dysphagia, only occur in the later stages of Parkinson’s disease. It has been found that some individuals may experience disordered swallowing early on, making it one of the first symptoms of the disease. The primary difficulty faced by most people with dysphagia is swallowing solid foods. They often describe a sensation of food getting stuck in their throat or chest. In more severe cases, food and liquids may go down the wrong way, leading to aspiration. The presence of dysphagia not only makes it challenging to take medications but can also result in malnutrition if left untreated.
