Affluence, age, and motor neuron disease.
by over fivefold (figure), and the rises were larger in middle and older age than in children and young adults.3 This discrepancy therefore indicates that the rises in asthma mortality cannot simply be related to increased incidence or prevalence of severe asthma requiring hospital admission. Assuming that data on asthma mortality are satisfactorily reliable, and that the determinants of hospit...
متن کاملParental age and motor neuron disease.
A case-control approach was used to study the relationship between parental age and motor neuron disease (MND) in a nationally representative sample of men. [The method, involving a search for parents' records in the NHS Central Register, is new and may be of interest in other conditions where parental age is thought to play a part.] The parents of men who died of MND in 1979 were not older tha...
متن کاملMotor Neuron Disease
Neurologists in the 19th century recognized that muscle weakness could be due to primary disorders of muscle or secondary to loss of neuromuscular integrity, as happens when peripheral nerves are cut or when motor neurons degenerate. Furthermore, it was observed that there are forms of motor neuron degeneration which selectively affect upper motor neurons or lower motor neurons. A combination o...
متن کاملAssessing motor neuron disease.
Hadjikoutis and Wiles draw attention to a number of circumstances in which the serum chloride and bicarbonate can be misleading. They do not mention that they will also be misleading if they are measured when hypercapnia is increasing or decreasing. An exacerbation of hypercapnia will take 4 – 6 days to raise the serum bicarbonate and lower the serum chloride to new steady levels. 1 How long it...
متن کاملMotor neuron disease
Motor neuron disease (MND) represents one ofthe major unsolved problems in neurology. The literature is characterized by numerous speculative theories, mostly derived by analogy with other recognized causes of motor neuron death such as poliomyelitis, or from toxic exposures such as lead poisoning. However, analogous reasoning of this type has not, so far, given insights into MND itself, or res...
