what is the full form of als disease
Amyotrophic lateral sclerosis Amyotrophic lateral sclerosis (ALS), also known as motor neurone disease (MND), and Lou Gehrig's disease, is a specific disease which causes the death of neurons controlling voluntary muscles.[3][5][11] Some also use the term motor neuron disease for a group of conditions of which ALS is the most common.[2] ALS is characterized by stiff muscles, muscle twitching, and gradually worsening weakness due to muscles decreasing in size.[2] This results in difficulty speaking, swallowing, and eventually breathing.[2][3]
Huntington's disease Huntington's disease (HD), also known as Huntington's chorea, is an inherited disorder that results in death of brain cells.[4] The earliest symptoms are often subtle problems with mood or mental abilities.[1] A general lack of coordination and an unsteady gait often follow.[2] As the disease advances, uncoordinated, jerky body movements become more apparent.[1] Physical abilities gradually worsen until coordinated movement becomes difficult and the person is unable to talk.[1][2] Mental abilities generally decline into dementia.[3] The specific symptoms vary somewhat between people.[1] Symptoms usually begin between 30 and 50 years of age, but can start at any age.[4][3] The disease may develop earlier in life in each successive generation.[1] About eight percent of cases start before the age of 20 years and typically present with symptoms more similar to Parkinson's disease.[3] People with HD often underestimate the degree of their problems.[1]
