Magnana symptom is a term coined by the French psychiatrist J.J.V. Magnan in 1892. It describes a state of chronic irresponsibility and indifference to one's duties and affairs.
People suffering from mañana symptoms often put off important tasks and decisions until later, saying “I’ll do it tomorrow” or “Tomorrow, tomorrow.” They demonstrate a chronic inability to complete things, and show apathy and indifference to the consequences of their actions or inactions.
This symptom is often observed in some mental illnesses such as depression, anxiety disorders, and personality disorders. However, it can also manifest itself in healthy people as a character trait or habit of always putting things off until later.
Manyana symptoms can be overcome through willpower, developing habits of discipline and planning. In severe cases, psychotherapy and drug treatment of the underlying disease that caused this symptom are required.
