Total 14 clinical symptoms reported for Spinocerebellar ataxia type 40  Frequent (14)

Broad-based gait	An abnormal gait pattern in which persons stand and walk with their feet spaced widely apart. This is often a component of cerebellar ataxia.   Synonyms:Broad based gait; Wide based gait; Wide based walk; Wide-based gait	Frequent
Dysarthria	Dysarthric speech is a general description referring to a neurological speech disorder characterized by poor articulation. Depending on the involved neurological structures, dysarthria may be further classified as spastic, flaccid, ataxic, hyperkinetic and hypokinetic, or mixed.   Synonyms:Difficulty articulating speech; Dysarthric speech	Frequent
Dysdiadochokinesis	A type of ataxia characterized by the impairment of the ability to perform rapidly alternating movements, such as pronating and supinating his or her hand on the dorsum of the other hand as rapidly as possible.   Synonyms:Difficulty performing quick and alternating movements; Dysdiadochokinesia	Frequent
Dysmetria	A type of ataxia characterized by the inability to carry out movements with the correct range and motion across the plane of more than one joint related to incorrect estimation of the distances required for targeted movements.   Synonyms:Lack of coordination of movement	Frequent
Functional motor deficit	Synonyms:Functional motor problems	Frequent
Gait ataxia	A type of ataxia characterized by the impairment of the ability to coordinate the movements required for normal walking. Gait ataxia is characteirzed by a wide-based staggering gait with a tendency to fall.   Synonyms:Ataxia of gait; Ataxic gait; Inability to coordinate movements when walking	Frequent
Hyperreflexia	Hyperreflexia is the presence of hyperactive stretch reflexes of the muscles.   Synonyms:Increased deep tendon reflexes; Increased reflexes	Frequent
Intention tremor	A type of kinetic tremor that occurs during target directed movement is called intention tremor. That is, an oscillatory cerebellar ataxia that tends to be absent when the limbs are inactive and during the first part of voluntary movement but worsening as the movement continues and greater precision is required (e.g., in touching a target such as the patient's nose or a physician's finger).	Frequent
Neurological speech impairment	Synonyms:Speech disorder; Speech impairment; Speech impediment	Frequent
Pontocerebellar atrophy	Atrophy affecting the pons and the cerebellum.   Synonyms:Cerebellopontine atrophy	Frequent
Scanning speech	An abnormal pattern of speech in which the words are as if measured or scanned; there is a pause after every syllable, and the syllables themselves are pronounced slowly.   Synonyms:Explosive speech	Frequent
Spastic paraparesis	This section is currently in development.	Frequent
Unsteady gait	Synonyms:Gait instability; Unsteady walk	Frequent
Vertical supranuclear gaze palsy	A supranuclear gaze palsy is an inability to look in a vertical direction as a result of cerebral impairment. There is a loss of the voluntary aspect of eye movements, but, as the brainstem is still intact, all the reflex conjugate eye movements are normal.   Synonyms:Vertical gaze palsy	Frequent
