Dysfunction of autonomic nervous system is an important non motor feature of Parkinson' disease (PD). Lewy body formation is widely distributed in hypothalamus and in sympathetic and parasympathetic systems. Animal studies suggest a link between hypothalamus sensing of substrates and glucose metabolism. Thus, hypothalamus lesions could lead to change in glucose metabolism. Recently, we showed that fasting blood glucose level was significantly higher in PD patients than in control group suggesting that glucose tolerance may be impaired in PD. Some studies provided evidence for higher diabetes prevalence in PD patients whereas others showed no difference or a reduced risk of diabetes prevalence in PD patients compared to healthy subjects.
So, the risk that a PD patient develops a glucose intolerance or a diabetes is not clearly established and merit to be studied considering the damageable consequences for patient healthy.
The aim of this prospective study was to determine the risk that a PD patient develop a glucose intolerance or a diabetes compared to a matched control group, using an oral glucose tolerance test (OGTT).
Inclusion visit :
- Clinical examination/ Interview on health and medical history
- Complete UPDRS, MMS
- Biologic check up
All patients were studied in the postabsorptive state after a 10-h overnight fast.
On the day of the experiment, patients did not receive their treatment. One catheter was inserted for blood sample collections. Patients ingested then 75 g of glucose.
Blood samples were collected for plasma glucose and plasma insulin concentration analyses at T0, T30, T60, T90, T120, T150 and T180. Urinary glucose was researched at T0 and T120.
In parallel, a dysautonomia evaluation of each patient was made (SCOPA AUT questionnaire, Tilt test).

In bariatric practice, a preoperative weight loss of at least 5% is recommended. However, the hypocaloric diets prescribed vary and no consensus exists. This study examined the efficacy of preoperativ...
Preliminary evidence suggests that diet manipulation may influence motor and nonmotor symptoms in PD, but conflict exists regarding the ideal fat to carbohydrate ratio.
Epidemiological studies suggest an association of certain foods with the risk of Parkinson's disease. Also, a number of studies revaeled positive effects on disease progression by caffeine, higher uri...

Proteins associated with sporadic or familial cases of PARKINSON DISEASE.
A diet that contains limited amounts of fat with less than 30% of calories from all fats and less than 10% from saturated fat. Such a diet is used in control of HYPERLIPIDEMIAS. (From Bondy et al, Metabolic Control and Disease, 8th ed, pp468-70; Dorland, 27th ed)
A biochemical phenomenon in which misfolded proteins aggregate either intra- or extracellularly. Triggered by factors such as MUTATION, POST-TRANSLATIONAL MODIFICATIONS, and environmental stress, it is generally associated with ALZHEIMER DISEASE; PARKINSON DISEASE; HUNTINGTON DISEASE; and TYPE 2 DIABETES MELLITUS.
A diet that contains limited amounts of protein. It is prescribed in some cases to slow the progression of renal failure. (From Segen, Dictionary of Modern Medicine, 1992)
