You will be given a definition of a task first, then some input of the task.
Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).

Abstract: A new right hemisphere symptom is reported. Five stroke patients with lesions in the perisylvian cortico-subcortical or thalamic region of the right hemisphere produced linguistically correct but semantically loose writing. The behaviour was initiated by subtle prompting and continued semiautomatically. A possible mechanism underlying this hypergraphia is discussed.
Which is the apt title for the abstract? option1: Hypergraphia: a right hemisphere syndrome. option2: Association of low blood manganese concentrations with epilepsy.
Output:
Hypergraphia: a right hemisphere syndrome.
