As the foraging reflex is linked to the search for food and comfort, its non-integration can lead to poor regulation of stress and anxiety, especially when there is sensory stimulation on the face. In some cases, adults may adopt compulsive oral behaviors, such as chewing gum, objects or nails.  

The asymmetrical tonic neck reflex can cause tension in the neck and shoulder region, leading to frequent migraines and neck pain. In adults, it can manifest itself as difficulties in following lines when reading, or clumsy handwriting with poor hand-eye coordination. The asymmetrical tonic neck reflex is linked to the development of the frontal lobe, which is responsible for executive functions such as attention and concentration. If this reflex persists, it can lead to difficulties in concentrating on complex tasks, organizing thoughts and remaining attentive for long periods. Bilateral movements (involving both sides of the body) such as running, swimming, or even typing at the computer can become more difficult to perform smoothly and synchronously.

People with a non-integrated glabellar reflex may experience hypersensitivity in the forehead and eyes. This can make activities such as applying make-up, washing the face or even wearing glasses uncomfortable. If the glabellar reflex persists, excessive blinking may occur when the forehead is touched or even in response to simple stimuli, such as light or other light visual or tactile stimuli. This can be troublesome in social interactions and daily activities.

Non-integrated plantar skin reflexes in adults may indicate underlying neurological disorders, such as damage to the central nervous system. Symptoms include problems with coordination, walking and pain in the feet, as well as plantar hypersensitivity.

Beyond the physical symptoms, unintegrated archaic reflexes can have a significant impact on emotional management and social relationships. Not being able to do as others do, either through inability or uncontrollable reactions, can affect our self-confidence, make us feel different or inadequate, and lead to socially awkward situations. 

For example, an individual whose Moro reflex is always present may feel in a constant state of alert, which can make social interactions more complicated. This hypervigilance can lead to flight or avoidance behaviors, or difficulties in dealing with conflict in a calm, rational manner. Affected adults may also be more prone to disproportionate emotional responses, feel overwhelmed more easily, and have difficulty handling stressful situations in a composed manner.
