Acetyl-leucine or a pharmaceutically acceptable salt thereof for improved mobility and cognitive function
The present disclosure is directed to acetyl-leucine or a pharmaceutically acceptable salt thereof for use in improving cognitive function, mobility, or cognitive function and mobility in a subject, for example, in an elderly subject.
1. A method of treating a mobility disorder associated with ageing in a subject in need thereof comprising:
(a) identifying the subject having the mobility disorder associated with ageing;
(b) taking a baseline measurement of the subject's mobility using one or more tests;
(c) administering a therapeutically effective amount of acetyl-leucine or a pharmaceutically acceptable salt thereof to the subject for a treatment duration;
(d) measuring the subject's mobility using the one or more tests after the subject is treated; and
(e) comparing the subject's mobility after treatment to the baseline measurement to determine if there is an improvement in the subject's mobility;
wherein the subject does not have vertigo or a neurological or neurodegenerative disease, disorder or condition, and
wherein the mobility disorder associated with ageing is chosen from decreased stability, unsteadiness while walking, senile gait disorder, increase in the coefficient of variability of gait velocity or cadence, and pre-disposition to falls.
2. The method of claim 1 , wherein the subject's mobility improves after treatment by at least 10% compared to the baseline measurement.
3. The method of claim 1 , wherein the acetyl-leucine is administered at least two times a day to achieve a total daily dose of from about 1.5 g to about 10 g.
4. The method of claim 1 , wherein the acetyl-leucine is administered at least two times a day to achieve a total daily dose of from about 4.5 g to about 10 g.
5. The method of claim 1 , wherein the treatment duration is at least 2 weeks, at least 7 weeks, or continuous treatment.
6. The method of claim 1 , wherein the subject is an elderly subject or a well elderly subject.
7. The method of claim 1 , wherein the subject further has an improvement in cognitive function because of administering the therapeutically effective amount of acetyl-leucine or a pharmaceutically acceptable salt thereof to the subject for the duration of treatment.
8. A method of treating a mobility disorder associated with ageing in a subject in need thereof comprising:
identifying the subject having the mobility disorder using one or more tests; and
administering a therapeutically effective amount of acetyl-leucine or a pharmaceutically acceptable salt thereof to the subject for a treatment duration;
wherein the subject does not have vertigo or a neurological or neurodegenerative disease, disorder or condition, and
wherein the mobility disorder associated with ageing is chosen from decreased stability, unsteadiness while walking, senile gait disorder, increase in the coefficient of variability of gait velocity or cadence, and pre-disposition to falls.
9. The method of claim 8 , wherein the treatment duration is at least 2 weeks, at least 7 weeks, or continuous treatment.
