Nerve Disease ALS and Gradual Loss of Muscle Function
Around 20%–30% have bulbar symptoms at onset—this is less common in younger patients, but affects more than 40% of those over 70 years.1 Virtually all patients will develop bulbar symptoms with disease progression. • progressive muscle atrophy with only lower motor neuron signs initially; some patients develop later lower motor neurone signs • primary lateral sclerosis, with predominantly upper motor neuron features, and • progressive bulbar palsy, with degeneration of bulbar nuclei and preservation of anterior horn cell and upper motor neuron function. If you're hit with a muscle cramp, it will get your attention right away. Whether they come at night or during the day, cramps can affect various muscle groups.

Spinal and bulbar muscular atrophy (SBMA, or Kennedy's disease) is an X-linked motor neuron disease typically presenting in adult men in the 3rd to 5th decades. The classic presentation is of slow progression of proximal weakness, bulbar weakness including asymmetric or symmetric facial weakness, and gynecomastia. Bulbar palsy refers to a range of different signs and symptoms linked to impairment of function of the cranial nerves IX, X, XI, XII, which occurs due to a lower motor neuron lesion in the medulla oblongata or from lesions of the lower cranial nerves outside the brainstem. These motor neurones are responsible for innervating the muscles of the tongue, pharynx and larynx (called the bulbar muscles) and so the symptoms of progressive bulbar palsy include wasting, weakness or stiffness of the tongue, difficulty with speaking and swallowing and problems with the thickness or amount of saliva Hi Everyone! Coleen here, and I've Got bALS! That means bulbar onset Amyotrophic Lateral Sclerosis or bulbar ALS. Unlike most people with ALS whose muscle weakness begin in their limbs, mine began in the bulbar region.

An individual with progressive bulbar palsy may have difficulty smiling, frowning, or otherwise showing emotion through facial expressions, resulting in what may be deemed as When the motor neurons affected are those of the diaphragm or of the intercostal muscles, respiratory paralysis occurs. Bulbar poliomyelitis results from viral attack on the medulla (bulb of the brain) or higher brain centers, with respiratory, vasomotor, facial, palatal, or pharyngeal disturbances. Poliomyelitis occurs throughout the world. Spinal and bulbar muscular atrophy (SBMA, or Kennedy's disease, named for the neurologist who published an early clinical description) is a disorder of slowly progressive muscle weakness associated with mild androgen insensitivity [Kennedy et al 1968, Harding et al 1982]. Only males are affected.

What are the symptoms of SBMA? SBMA causes weakness of the facial and swallowing muscles, as well as limb weakness. The bulbar nerves also innervate muscles involved in swallowing and facial muscles.
