Explanation:

• Myxedema: It is a complication of hypothyroidism. One of the physical manifestations can be thinning or absence of hair at the lateral margin of the eyebrows.
• Addison's disease: It is caused by deficient production of cortisol (and often aldosterone) by the adrenal cortex.
• Cushing's syndrome: It is due to excessive cortisol levels.
• Parkinson's disease: It is a neurodegenerative disorder mainly characterized by motor symptoms like tremors, bradykinesia, etc., and not typically associated with eyebrow hair loss or cortisol - related issues in the way described.
• Acromegaly: It is due to excessive growth hormone production, usually presenting with features like enlarged hands, feet, and facial features, not related to cortisol deficiency.
