Introduction:
Head tremor, either as an isolated symptom or as part of a symptomatic complex, occurs in patients with different neurological diseases. Little research has been carried out to analyse the clinical features of this neurological symptom.
Aim:
To review the symptomatology, aetiology and therapeutics of brain tremors.
Development:
Two main types of brain tremor can be distinguished: tremor of the whole brain (holocephalic tremor) and segmented brain tremor (tremor of the jaw, tongue, chin, soft palate, task-specific, orthostatic orolingual and undetermined). Essential tremor, the main cause of brain tremor, and dystonic tremor give rise to holocephalic-type tremor in the vast majority of cases. Brain tremor in Parkinsonism is characteristically of the segmented type. The effectiveness of the pharmacological treatment of brain tremor is very limited. Botulinum toxin is a promising therapy for brain tremors of any causation. In severe cases of brain tremor, functional surgery by means of deep brain stimulation of the intermediate ventral thalamic nucleus is useful, but must be performed bilaterally.
Conclusions:
The semiological characteristics of brain tremor are a valuable aid in the aetiological diagnosis. Pharmacological therapy is very limited. Botulinum toxin and functional surgery of the intermediate ventral thalamic nucleus are useful in selected patients.

Seizures l: Introduction
Muscles that Move the Head
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...
Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
