Final answer:
The signs and symptoms in Stage 2 of PWS include hypotonia, delayed motor development, feeding difficulties, excessive eating, cognitive deficits, behavioral problems, and sleep disturbances.
Step-by-step explanation:
The signs and symptoms in Stage 2 of Prader-Willi Syndrome (PWS) can vary but typically include:
- Hypotonia (lack of muscle tone)
- Delayed motor development
- Feeding difficulties
- Excessive eating and weight gain
- Cognitive deficits
- Behavioral problems
- Sleep disturbances
During this stage, individuals with PWS may also exhibit temperature instability, bradycardia, hypotension, irritability, and difficulty waking up from sleep. As the disease progresses, other symptoms such as seizures, stiff neck, and weakness on one side of the body may develop.
The signs and symptoms associated with Stage 2 of Prader-Willi Syndrome (PWS) typically emerge between the ages of 6 and 12. Developmental delays such as poor muscle tone and behavioral issues arise during this stage. These are often followed by the onset of an excessive appetite and food-seeking behaviors, which can result in rapid weight gain if not properly managed. Cognitive development in individuals with PWS may also be affected, which can be seen in terms of learning difficulties or deficits. Although PWS is a complex condition with no current cure, effective management, including growth hormone treatment and psychoactive medications, can greatly improve the quality of life for individuals with PWS.
