Symptoms of Asperger's disorder in adults include a marked impairment in social interactions, repetitive or restricted behavior or activity patterns, and a resulting impairment in important areas of function such as work or social life, according to Psych Central. Adults with Asperger's may also appear physically awkward.
To receive a diagnosis for Asperger's disorder as defined by the Diagnostic and Statistical Manual of Mental Disorders, individuals must experience qualitative social impairment in at least two of several manifestations, as stated by Psych Central. The first manifestation is a significant impairment of nonverbal cues such as eye contact, gestures, posture and facial expression. The second includes difficulty forming relationships with peers, and the third is a lack of the spontaneous sharing of achievements and enjoyment with others. Individuals may also have trouble with emotional or social reciprocity.
Those with Asperger's may have a preoccupation with a few restricted topics that are unusual in their subject matter or intensity, as confirmed by Psych Central. Individuals may have the strong need to adhere to routines or rituals in which others see little purpose, and they may be preoccupied with the parts of an object rather than the whole. Adults who believe they may have Asperger's should consult with a qualified psychologist for diagnosis and coping mechanisms that may improve quality of life.
