Which characteristic is not associated with Cushing's syndrome?

Cushing's syndrome is characterized by an overproduction of cortisol, which leads to various physiological and physical changes in the body. One of the hallmark features of this syndrome is the development of a rounded face, often referred to as "moon facies," alongside other distinct characteristics such as heavy body shape and atrophied skeletal muscle, particularly in the limbs, due to muscle breakdown.

The presence of atrophied lymph nodes and the distribution of fat and muscular changes in Cushing's syndrome are also notable. In the context of the condition, the body undergoes specific alterations in muscle mass and fat distribution, which are common consequences of excess cortisol levels.

Infrequent blinking and staring eyes do not typically connect with Cushing's syndrome. The physiological manifestations of Cushing's are more aligned with metabolic and muscular changes rather than neurological or ophthalmic symptoms like those mentioned. Thus, the characteristic of staring eyes with infrequent blinking is not associated with Cushing's syndrome and stands apart from the other physical manifestations related to this condition.
