Spasmodic dysphonia can also be misdiagnosed as voice tremor. [28] The movements that are found in this disorder are typically rhythmic in nature, as opposed to the muscle spasms of spasmodic dysphonia. [25] It is important to note that voice tremor and spasmodic dysphonia can co-occur in some patients. [25]
Children with childhood dementias suffer severe sleep disturbances, movement disorders (e.g. muscle spasms, tremors), deterioration of communication skills, loss of vision and hearing, mood disorders, psychosis (including hallucinations and delusions) and incontinence. [3] This situation can cause many emotional changes for parents and children.
Voice disorders [1] are medical conditions involving abnormal pitch, loudness or quality of the sound produced by the larynx and thereby affecting speech production. These include: These include: Vocal fold nodules
A tremor is an involuntary, [1] somewhat rhythmic muscle contraction and relaxation involving oscillations or twitching movements of one or more body parts. It is the most common of all involuntary movements and can affect the hands, arms, eyes, face, head, vocal folds, trunk, and legs.

Focal hand dystonia (also known as musician's or writer's cramp). single muscle or small group of muscles in the hand
The main underlying cause of essential tremor is not clear, but many cases seem to be familial. [37] About half of the cases are due to a genetic mutation and the pattern of inheritance is most consistent with autosomal dominant transmission, meaning patients with Essential Tremor have around a 50% chance to pass it on to their children. [38]
A neurological examination would show evidence of muscle rigidity; weakness; and abnormal postures, movements, and tremors. If other family members are also affected, this may help determine the diagnosis. Genetic tests can confirm an abnormal gene causing the disease. However, this test is not yet widely available.
Parkinsonism is a clinical syndrome characterized by tremor, bradykinesia (slowed movements), rigidity, and postural instability. [1] [2] Both hypokinetic (bradykinesia and akinesia) as well as hyperkinetic (cogwheel rigidity and tremors at rest) features are displayed by Parkinsonism. [3]
