Bipolar Disorder Symptoms and Signs

Unusually High Excitement Can Be a Warning Sign. Experiencing intense euphoria without a clear reason may indicate an underlying mental health condition. In bipolar disorder, a person can shift from their usual self into a state of manic behavior. During these episodes, they may engage in risky actions or unintentionally put themselves and others in danger. Another warning sign is when an elevated mood lasts far beyond a normal timeframe—for example, remaining excessively giddy about a joke from a party that happened a week ago.
