Tremor: A systematic approach.

Background: Tremor is a common but complex involuntary movement disorder often first assessed by general practitioners (GPs). Due to its diverse causes and manifestations, an accurate assessment of a patient's tremor helps guide initial investigations and treatments.

Objective: The purpose of this paper is to equip GPs with a framework for the identification, diagnosis and management of different types of tremors.

Botulinum neurotoxin for the treatment of movement disorders.

Background: Botulinum neurotoxin (BoNT) is an exotoxin that causes neuromuscular weakness. BoNT serotypes A and B have been used for decades for the safe and effective treatment of various movement disorders, including some forms of focal dystonia. These conditions, such as cervical dystonia, hemifacial spasm, blepharospasm and spasmodic dysphonia, can have a substantial impact on patients' quality of life, but are often under-recognised.
