Introduction

• Parkinson's disease most often develops after age 50. It is one of the most common nervous system disorders of the elderly.

• Early in the course of the disease, the most obvious symptoms are movement-related; these include shaking, rigidity, slowness of movement and difficulty with walking and gait. Later, thinking and behavioral problems may arise, with dementia commonly occurring in the advanced stages of the disease, where depression is the most common psychiatric symptom. Other symptoms include sensory, sleep and emotional problems.

Neurodegenerative diseases including Parkinson’s disease represent a major target area for outcome improvement.

There is no cure for Parkinson's disease, but it can be managed and the symptoms of the disease can be relieved or reduced.

Levodopa/Carbidopa intestinal gel (Duodopa) is used to

treat advanced Parkinson’s disease.

Aim• The purpose of our study is to observe the benefits of

the use of enteral L-dopa infusion on non-motor symptoms for a period of six months at patients with advanced Parkinson’s disease. 

Material and method

• We performed a retrospective study of 18 patients with advanced Parkinson’s disease, hospitalized in Neurology Clinic of Targu Mures County Clinical Emergency Hospital which were selected for treatment with Duodopa.

• Each patient was questioned according to the “Non-Motor Symptom Assessment Scale for Parkinson’s Disease” during an interview at the beginning of treatment and after six months of treatement with Duodopa.

The used scale comprises 9 domains: • Cardiovascular • Sleep • Mood • Perceptual problems • Attention/Memory • Gastrointestinal tract• Urinary • Sexual function • MiscellaneousEach symptom included in this scale was scored

respecting the severity and the frequency.

Scores obtained at the beginning of treatment:

16

262

169

Scores obtained after six months of treatement

with Duodopa:

Interpretation:• Cardiovascular domain is the only with an unfavorable

progres: 16–>26 • Sleep\fatigue: 262 –>212• Mood\cognition: 169 –>140• Perceptual problems\ hallucinations: 25 –>19• Attention/Memory: 77 –>71 • Gastrointestinal tract: 160 –>130• Urinary: 192 –>134• Sexual function: 181 –>121 the most significant

improvement • Miscellaneous: 151 –>142

Conclusions:• The use of enteral L-dopa infusion in the treatment of

advanced Parkinson’s desease has developed over the last 20 years.

• By providing a continuous flow of medication directly to the intestines, where it is absorbed, Duodopa can help maintain a constant level of levodopa in the blood and by that it decreases the number of times a patient alternates between stiffness and uncontrolled movements (on/off).

• After six months of treatement with Duodopa intestinal gel we noticed a significant improvement of non motor symptoms in patients with advanced Parkinson's disease
