have social security disability cases reviewed more frequently in order to stop un-needed benfits from being dispersed.

From SSA.GOV:
The frequency of reviews depends on the nature and severity of your medical condition and whether it is expected to improve.
•If improvement is expected, your first review generally will be six to 18 months after the date you became disabled.
•If improvement is possible, but cannot be predicted, your case will be reviewed about once every three years.
•If improvement is not expected, your case will be reviewed once every seven years.

Cases should be reviewed every 6 months for cases in which improvement is expected. This would seriously help in cutting the amount of SS that is paid out without need.
