Depending on the age of the person, abnormal mental development can take different forms. Abnormal mental development can manifest in different ways depending on the individual and the specific situation.

In an interview with HT Lifestyle, Rohini Rajeev, Senior Psychiatrist and Founder of The Able Mind emphasized, “It is important for parents to understand and acknowledge developmental milestones (cognitive, emotional/social, speech/language, motor skills etc.). Growth milestones (physical parameters) are different and most children fall within the range. While rare minor developmental delays should not be cause for alarm, attention should be paid to frequent, multiple and significant developmental milestone delays. Seeing your child’s developmental delays can be upsetting and challenging for parents.
According to him, the following are some signs to pay attention to so that early interventions can be initiated, especially in the case of neurodevelopmental delays and the child can be supported and the parents can be properly guided:
- Sudden and persistent changes in behavior
- Not responding to calls and not maintaining eye contact
- Expressing shyness and lack of facial expression negatively
- Lack of social interaction: The child shows no interest in social interaction with other people, avoids any interaction for long periods of time, does not smile, or does not respond to others’ attempts to communicate.
Regarding teenagers, Dr Vrishali Bichkar, consultant pediatrician and neonatologist at Motherhood Hospital, Lullanagar, Pune, warns to be aware of these warning signs of abnormal mental development.
• Feeling sad or low: If a child feels sad for no reason, it could be due to depression or some other mental illness.
Confused thinking or inability to concentrate: Having these red flags indicates that you need to see a doctor without any delay.
• Feeling anxious or guilty: If you often feel anxious or guilty, you need to take care of your mental health.
• Extreme mood swings and withdrawal There are problems with your mental health from activities you used to love. A child may be happy but the next moment, he may be angry or sad.
Fatigue: If you often feel tired and unable to perform your daily activities easily then you need to be aware. Unusual fatigue will indicate that something is wrong with you.
• Lack of ability to cope with stress Exams or peer pressure can also indicate mental health problems.
