Regression means a child loses skills they had already mastered after a period of typical development, and any skill loss deserves a prompt review. FASD is a lifelong condition caused by alcohol exposure in pregnancy, present from birth, affecting learning, behaviour, growth and sometimes facial features. The core difference: regression is a change over time, while FASD has shaped development from the start. Both benefit from early, individual assessment.","answer_md":"*Both can change how a young child develops — but one is about losing skills already gained, and the other is present from before birth.*\n\n## In short\n**Developmental regression** means a child *loses skills they had already mastered* — words they used to say, ways they used to play or connect — after a period of typical development. **Fetal Alcohol Spectrum Disorder (FASD)** is a lifelong condition caused by alcohol exposure during pregnancy, present from birth, that affects learning, behaviour, growth and sometimes facial features. The key difference: regression is about a *change over time* (a child going backwards), while FASD is a *cause-based condition* that has shaped development from the very start.\n\n## How they differ in everyday life\n**Developmental regression** is noticed as a *loss*. A toddler who waved, pointed and said a few words gradually stops doing those things; a child who made eye contact and enjoyed cuddles seems to withdraw. Because losing skills can sometimes signal an underlying medical or neurological issue, regression always deserves a *prompt* developmental and medical review — not a wait-and-see approach.\n\n**FASD**, by contrast, is not a sudden change. It is linked to alcohol exposure in pregnancy and is recognised through a pattern that may include difficulties with attention, memory, learning, impulse control, motor coordination, slower growth, and in some children, characteristic facial features. The challenges are present from infancy and unfold as the child grows, rather than appearing after a stretch of typical development.\n\nSo the questions clinicians ask differ. For regression: *What skills were there, and when did they fade?* For FASD: *Is there a known history of prenatal alcohol exposure, and does the overall developmental picture fit?* A child can, of course, have more than one thing going on, which is why a careful, individual assessment matters.\n\n## When to seek help\nFor **regression** — any loss of language, social connection, play or motor skills your child once had — seek a review *soon*, as some causes are time-sensitive. For **FASD** — if there was alcohol exposure in pregnancy and you notice learning, attention, growth or behaviour concerns — an early assessment opens the door to support and strategies that genuinely help. Early help is empowering in both situations.\n\n## The Pinnacle way\nThis is general information, not a diagnosis — a clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care, never from an app or form.
