Learning disabilities are neurologically-based processing problems. These processing problems can interfere with learning basic skills such as reading, writing and math. They can also interfere with higher-level skills such as organization, time planning, abstract reasoning, long or short-term memory and attention. It is important to realize that learning disabilities can affect an individual’s life beyond academics and impact relationships with family, friends, and the workplace.
Since difficulties with reading, writing and math are recognizable problems during the school years, the signs and symptoms of learning disabilities are most often diagnosed. However, some individuals do not receive an evaluation until they are in post-secondary education or adults in the workforce.
Other individuals with learning disabilities may never receive an evaluation and go through life never knowing why they have difficulties with academics and may be having problems in their jobs or relationships with family and friends.
Learning disabilities should not be confused with learning problems that primarily result from visual, hearing, or motor handicaps; intellectual disability; emotional disturbance; or environmental, cultural or economic disadvantages.
In Federal law, under the Individuals with Disabilities Education Act (IDEA), the term is “specific learning disability,” one of 13 categories of disability under that law.
Types of Learning Disabilities
Auditory Processing Disorder (APD)
Also known as Central Auditory Processing Disorder, this condition adversely affects how sound that travels unimpeded through the ear is processed or interpreted by the brain. Individuals with APD do not recognize subtle differences between sounds in words, even when the sounds are loud and clear enough to be heard. They can also find it difficult to tell where sounds are coming from, make sense of the order of sounds, or block out competing background noises. Learn more about Auditory Processing Disorder
A specific learning disability affects a person’s ability to understand numbers and learn math facts. Individuals with this type of LD may also have poor comprehension of math symbols, struggle with memorizing and organizing numbers, have difficulty telling time, or have trouble counting.

A specific learning disability affects a person’s handwriting ability and fine motor skills. Problems may include illegible handwriting, inconsistent spacing, poor spatial planning on paper, poor spelling, difficulty composing writing, and thinking and writing at the same time.

A specific learning disability that affects reading and related language-based processing skills. The severity can differ in each individual but can affect reading fluency, decoding, reading comprehension, recall, writing, spelling, and sometimes speech and can exist along with other related disorders. Dyslexia is sometimes referred to as a Language-Based Learning Disability. Learn more about Dyslexia
Language Processing Disorder
A specific type of Auditory Processing Disorder (APD) in which there is difficulty attaching meaning to sound groups that form words, sentences, and stories. While an APD affects the interpretation of all sounds coming into the brain, a Language Processing Disorder (LPD) relates only to language processing. LPD can affect expressive language and receptive language. Learn more about Language Processing Disorder
Non-Verbal Learning Disabilities
A disorder is usually characterized by a significant discrepancy between higher verbal skills and weaker motor, visual-spatial and social skills. Typically, an individual with NLD (or NVLD) has trouble interpreting nonverbal cues like facial expressions or body language and may have poor coordination.

Visual Perceptual/Visual Motor Deficit
A disorder affects the understanding of information that a person sees or the ability to draw or copy. A characteristic is seen in people with learning disabilities such as Dysgraphia or Non-verbal LD; it can result in missing subtle differences in shapes or printed letters, losing place frequently, struggles with cutting, holding pencil too tightly, or poor eye/hand coordination.

A disorder includes difficulty staying focused and paying attention, difficulty controlling behaviour and hyperactivity. Although ADHD is not considered a learning disability, research indicates that 30-50 percent of children with ADHD also have a specific learning disability. The two conditions can interact to make learning extremely challenging. Learn more about ADHD
An inefficiency in the cognitive management systems of the brain affects a variety of neuropsychological processes such as planning, organization, strategizing, paying attention to and remembering details, and managing time and space. Although not a learning disability, different patterns of weakness in executive functioning are almost always seen in the learning profiles of individuals who have specific learning disabilities or ADHD.

Three types of memory are important to learning. Working memory, short-term memory, and long-term memory are used in the processing of both verbal and non-verbal information. If there are deficits in any or all of these types of memory, the ability to store and retrieve information required to carry out tasks can be impaired. Learn more about Memory
