Attention - Deficit Hyperactivity Disorder (ADHD) is one of the most common childhood behavioral disorders diagnosed in the psychiatry outdoor setting, affecting 5-7% of school - aged children[1]. It is a neuro - developmental disorder that runs a chronic course and causes significant impairments across various domains of day to day functioning. The symptoms of ADHD are divided into two predominant categories: inattention and hyperactivity/impulsivity. Inattention is divided intwo subtypes i.e. focused and sustained/ Executive dysfunction.

Porphyrias are a group of inherited or acquired disorders of certain enzymes in the heme bio-synthetic pathway (also called porphyrin pathway). They are broadly classified as acute (hepatic) porphyrias and cutaneous (erythropoietic) porphyrias, based on the site of the overproduction and accumulation of the porphyrins or their chemical precursors. They manifest with either neuropsychiatric complications or skin problems or occasionally both. A clinically induced and histologically identical condition is called pseudo porphyria which is characterized by normal serum and urine porphyrin levels.
