1.Overeating Behavior and Striatal Dopamine with 6-[F]-Fluoro-L-m-Tyrosine PET.
Wilcox CE1, Braskie MN, Kluth JT, Jagust WJ. J Obes. 2010;2010. pii: 909348. doi: 10.1155/2010/909348. Epub 2010 May 4.
Eating behavior may be affected by dopamine synthesis capacity. In this study, 6-[(18)F]-fluoro-L-m-tyrosine (FMT) positron emission tomography (PET) uptake in striatal subregions was correlated with BMI (kg/m(2)) and an estimate of the frequency of prior weight loss attempts in 15 healthy subjects. BMI was negatively correlated with FMT uptake in the dorsal caudate. Although the association between BMI and FMT uptake in the dorsal caudate was not significant upon correction for age and sex, the association fell within the range of a statistical trend. Weight loss attempts divided by years trying was also negatively correlated with FMT uptake in the dorsal putamen (P = .05). These results suggest an association between low dorsal striatal presynaptic dopamine synthesis capacity and overeating behavior.
2.Freezing of Gait in Parkinson's Disease Is Associated with Reduced 6-[(18)F]Fluoro-l-m-tyrosine Uptake in the Locus Coeruleus.
Ono SA1, Sato T2, Muramatsu S3. Parkinsons Dis. 2016;2016:5430920. doi: 10.1155/2016/5430920. Epub 2016 Feb 23.
Freezing of gait (FOG) is a common disorder in Parkinson's disease (PD) and could be attributed to a reduction in brain noradrenaline. The aim of this study was to determine the relationship between aromatic l-amino acid decarboxylase (AADC) activity in the locus coeruleus (LC) and FOG in PD using high-resolution positron emission tomography with an AADC tracer, 6-[(18)F]fluoro-l-m-tyrosine (FMT). We assessed 40 patients with PD and 11 age-matched healthy individuals. PD was diagnosed based on the UK Brain Bank criteria by two movement disorder experts. FOG was directly observed by the clinician and assessed using a patient questionnaire. FMT uptake in the LC, caudate, and putamen was analyzed using PMOD software on coregistered magnetic resonance images. FOG was present in 30 patients. The severity of FOG correlated with the decrease of FMT uptake in the LC regardless of disease duration and the severity of other motor impairments, indicating dysfunction of the noradrenergic network in FOG.
