5. History of seizure (other than infantile febrile seizures), any tic disorder, or a current diagnosis and/or family history of Tourette's Disorder.

6. Known history of symptomatic cardiovascular disease, advanced arteriosclerosis, structural cardiac abnormality, cardiomyopathy, serious heart rhythm abnormalities, coronary artery disease, transient ischaemic attack or stroke, or other serious cardiac problems that may place them at increased vulnerability to the sympathomimetic effects of a stimulant drug.

7. Family history of sudden cardiac death or ventricular arrhythmia.

8. Known cerebrovascular disorders such as cerebral aneurysm, vascular abnormalities including vasculitis or history of stroke.

9. Diagnosis of glaucoma.

10. Diagnosis of phaeochromocytoma.

11. Current abnormal thyroid function, as defined as abnormal screening thyroid stimulating hormone (TSH) and thyroxine (T4).

12. Current marked anxiety, tension and/or agitation.

17. Use of tobacco in any form (e.g., smoking or chewing) or other nicotine-containing products in any form (e.g., gum, patch) within 30 days prior to the Screening visit.

18. Routine consumption of more than 300mg of caffeine per day or subjects who experience caffeine withdrawal headaches or have a history of caffeine withdrawal headaches.
