The vast majority of mental disorders, like schizophrenia, first appear during the first three decades of life. Defining the precise timing of this symptomatic start is central to understanding a patient's health trajectory. In medicine, understanding **what is the meaning of age of onset** is fundamental, as it refers to the age at which a disease, disorder, or condition first manifests or is diagnosed.

Over 100,000 babies are born with severe thalassemia globally each year, highlighting the condition's significant impact. The critical question of **at what age do thalassemia symptoms appear?** depends largely on the specific genetic mutation and severity, with manifestations ranging from severe anemia in infancy to lifelong, symptom-free carrier states.

Affecting approximately 1 in 2 million people worldwide, fibrodysplasia ossificans progressiva (FOP) presents a unique challenge across a patient's lifetime. The question of **what is the age range for fibrodysplasia ossificans progressiva?** is best understood by examining its progressive, age-dependent course. The characteristic congenital malformation of the big toes offers the earliest diagnostic clue, visible from birth, before the onset of significant bone formation.

The age of onset refers to the time period at which an individual first experiences the symptoms of a disease or disorder. This critical medical concept, which addresses the question, "What is the age of onset of illness?," varies significantly across different health conditions and populations.

ITP exhibits a bimodal age distribution, with peaks occurring in early childhood and later adulthood. So, **what is the age of onset of ITP?** It most commonly peaks in young children, often after a viral infection, and again later in adulthood, where it frequently presents as a more chronic condition.

While chronic granulomatous disease (CGD) is most often diagnosed before age five, the age of onset for granulomatous disease varies widely depending on the specific condition, affecting individuals from infancy to late adulthood. This complexity requires understanding the different types of granulomatous diseases and their unique characteristics.

Over 45% of deaths in the developed world are linked to fibrotic diseases, which cause irreversible scarring in organs. Understanding **what age does fibrosis start** requires recognizing that the answer varies significantly depending on the specific type of fibrosis, from genetic forms at birth to age-related conditions later in life.

According to the National Institutes of Health, while Myalgic Encephalomyelitis (ME), or Chronic Fatigue Syndrome (CFS), can affect all ages, the average age of onset is around 33 years. This debilitating, multi-system condition is marked by severe, unexplained fatigue not relieved by rest.

According to the Centers for Disease Control and Prevention (CDC), ME/CFS affects children, adolescents, and adults of all ages. Understanding **what age can you get chronic fatigue syndrome** is crucial for early detection and proper management, as different age groups may experience distinct symptoms and challenges. Though it is most commonly diagnosed between the ages of 40 and 60, it's not a disorder exclusive to older adults.
