Parkinson’s disease is a progressive, neurodegenerative disease resulting from a reduction of dopamine levels within the basal ganglia. It affects 1-2 % of the world’s population over the age of sixty. Number of people affected with Parkinson’s disease is expected to rise in relation to the aging population. Although Parkinson’s disease is mainly characterized by the primary, motor symptoms, a large majority of the patients will develop hypokinetic dysarthria, a motor speech disorder affecting voice quality and speech production. Multidisciplinary approach in treating patients with Parkinson’s disease includes speech and language therapy. Hypokinetic dysarthria is characterized by reduced loudness of speech, breathy and harsh voice, imprecise consonants, monotonous voice, variable speech rate and disfluency. These changes are a result of muscle rigidity, sensory processing deficits and troubles with self monitoring of output. Symptoms of hypokinetic dysarthria worsen with progression of the disease and have a negative impact on quality of life, social contact and communication of people with Parkinson’s disease. Pharmacological and surgical treatment were shown to have very limited impact on speech symptoms, so the focus switched to speech therapy. Speech therapy can target all levels of speech production process, but it usually focuses on respiration, fonation and articulation. The most effective interventions are intensive in nature, with simple and clear instructions. They consider the sensory processing deficits in people with Parkinson’s disease, impairment of self monitoring and focus on attention-to-effort in voice production. Lee Silverman Voice Treatment (LSVT) is currently considered the golden standard in speech therapy of patients with Parkinson’s disease. Even though speech therapy is successful in treating symptoms of hypokinetic dysarthria, only a small percentage of people diagnosed with Parkinson’s disease are referred to a speech language pathologist for an assessment and treatment. Raising awareness of the general public and experts included in the diagnosis and treatment of Parkinson’s disease is therefore important for effective and timely treatment of voice and speech symptoms in patients diagnosed with Parkinson’s disease.
