Episodic ataxia type 1 (EA1) is a human dominant neurological syndrome characterized by continuous myokymia, episodic attacks of ataxic gait and spastic contractions of skeletal muscles that can be triggered by emotional stress and fatigue. This rare disease is caused by missense mutations in the
BACKGROUND
Neuromyotonia (NM), Isaacs-Zschoke-Mertens syndrome or continuous muscle fiber activity (CMFA), is a rare condition associated with VGKC-antibodies. Clinically, fasciculations, myokymias, muscle stiffness and a myotonic appearance of movements after contraction are typical findings. In
Familial episodic ataxias are unusual hereditary disorders of early onset characterized by recurrent episodes of ataxia. Most patients recover fully between attacks, but some may develop progressive ataxia with cerebellar atrophy. There are two subtypes of episodic ataxia: type 1 (EA1), with
Motor neuron hyperexcitability (MNH) indicates a disorder characterized by an ectopic motor nerve discharge on electromyogram (EMG). Here, we present a series of three cases of subacute MNH with mercury poisoning. The first case showed hyperhidrosis, insomnia, generalied myokymia, cramps, tremor,
Episodic ataxia type 1 (EA1) is a K(+) channelopathy characterized by a broad spectrum of symptoms. Generally, patients may experience constant myokymia and dramatic episodes of spastic contractions of the skeletal muscles of the head, arms, and legs with loss of both motor coordination and balance.
