Since this child has never developed attachment with the mother and other important care takers, he/she will have problems with making meaningful relationship with others. This child will be trying to make relationships with others but they will be superficial and temporary. He/ she will have trust issues, may not have empathy, will be angry, manipulative, will have a lot of anxiety and maladaptive problem solving ability. For all these he/she will require therapy

Basically the child will develop a 'bad object relation towards authority figures' as stated in technical terms. In simpler words, a number of bad effects may persist into adult life. Higher likelihood of depression and anxiety disorders, a generally pessimistic outlook towards life, world and future and possibly becoming a poor parent himself. These are some of the possibilities. Therapy can certainly help improve many of these problems and alleviate risk for others.

Mother is the most important being in a child's universe and deviated or defective mother child relationship can leave permanent scars on a child's psychological make up. It is extremely difficult to write details here so this is a briefer description. Generally, Most of such children grow up with significant anxiety and depressive issues. They lack confidence in not just establishing and maintaining relationships but also in simple day to day activities, they find it difficult to trust others and themselves too. They feel lonely and incomplete from inside, always striving to fill that hollowness but not knowing how. On the other hand, some of these children grow up to be vindictive, spiteful, full of resentment, they are short tempered, aggressive, expect high from self and others and strive hard to achieve acknowledgment from significant others. But there can be different combinations of symptomatology in different people. As far as therapy for such individuals is concerned, its a definitive yes. Hope this helps, good luck!
